Barker's Official Blog
Barker's Sponsored Rider, Juan Pirrunas Dominguez, and his skilled team took first place in the competitive sportsman quad class at the 2017 Baja 500. Words simply cannot express how excited and proud we are. We thank our lucky stars for having such a dedicated and skilled racer on our team, who pushes himself, his machine, and our exhausts to the limit, and time and time again excels. Of course, this race didn't play out without its own set of unique challenges and mishaps. Check out how Juan and Team 109A took down the competition and made it to the finish line, below.
Thank you so much! The whole team is thrilled about our Baja 500 win but this one is even more special because we were the first quad across the finish line which is our first overall finish ever!
I don’t know if you noticed but the whole right side of my jersey was torn due to a small crash around race mile 12! The fog was so thick that I ran a turn while I had 5th gear tapped! I was unable to make the full turn so I turned into a barbed wire fence. Thanks to some of the locals and police, I was able to get going again after about a minute. Just some bruises and some scratches and I was off again! Nothing happened to the quad thank God. [OR YOU, JUAN!!! WAY TO RECOVER!]
The silt in the first half of the course was so gnarly that our white quad turned into a pile of silt after a couple hundred miles. Our new Barker’s Exhaust allowed us to power through that stuff with no problem and made going through silt beds really fun! The whoops near San Felipe are always physically tough. Not only do they take a toll on the rider but they were mixed with 100+ degree weather that got our motor and shocks really hot. However, Baja ATV Rider’s Only set us up with plush Elka Suspension that made it easier to power through them for 200 miles!
We were the last quad off the line out of the 12 total quads that were registered for this Baja 500. At race mile 80, we were the second quad on the road and first overall on time. However, the top 4 quads in our class were less than 5 minutes apart which made for some serious racing for almost 300 miles until we started pulling away from the competition. We took over the physical overall lead around San Felipe and held it all the way to the finish line! It was nerve-racking because we did not want to blow our overall position so we held a smooth fast pace for the last half of the race.
The craziest thing I saw was coming up on a huge cow that was torn to pieces with guts laying all over the race course. The smell was so horrible that I gagged inside my helmet! Looked like a truck hit it at full speed during pre-running. It is actually kind of scary when rounding corners at over 80 mph and just praying to God you don’t run into a horse or cow. You will get killed instantly on a quad.
Well after my first crash in the morning, I rode a little more careful. Although my adrenaline was at full blast, I didn’t want to ruin our race for riding over my head. You can’t win a Baja 500 in the first 70 miles but you sure can end it! So our plan was to ride smooth and fast through the thick morning dust and that’s what we did. After starting last in our class, we came in first in class at race mile 80 and pushed through some of the gnarliest fog and dust I have ever seen!
The new round can looks awesome and gave the finishing touch to our race quad. We also noticed the clamp was easier to put on with the round can when compared to the oval design. It also gave the quad a sharper sound and felt more torque at the touch of the throttle. This gave us a huge advantage through the rocks and the sandy whoops around the San Felipe loop. The installation of the exhaust went smoothly and everything bolted right up. We just love the way the new round design looks, especially with the two-tone anodized exhaust cap. We could distinguish the sound of our quad through mountains and the wide open desert when it was coming hot into the pits. It just sounds much more powerful than any other exhausts the competition was running. It still looks brand new after 515 miles of racing Baja!
The team wants to give huge thanks to Barker’s Exhaust for their support in our 2017 Baja 500 effort. The whole team was really happy with the response the new design gave us compared to the oval exhaust we ran at the San Felipe 250 in April. Our sights are set for the Baja 1000 in November. The 50th running of the Baja 1000 will be a peninsula run this year that will start in Ensenada and finish in La Paz. We are expecting a 1300+ mile Baja 1000 course and the preparation for this adventure started right after we crossed the Baja 500 finish line first overall!

Even hotter and even more brutal than the San Felipe 250, the 2017 Baja 500 is fixing to be one of the greatest challenges yet for racers. This includes our sponsored rider, Juan Pirrunas Dominguez, but we're confident this man, his team, and their winning Honda TRX450R are prepped and ready to conquer.
We just wouldn't be doing our job if we didn't keep fans up to date on this incredible race and racer. So we reached out to Juan to learn more about his thoughts and plans going into the 2017 Baja 500. Here's what we learned.
This year’s Baja 500 is going to be a real challenge due to the very demanding course that SCORE International has put together. This year’s race course has all the obstacles that Baja has to offer. From running along the Pacific Ocean to pounding San Felipe whoops in 100+ degree weather. As always, Pirruñas Racing is preparing for the worst and expecting the unexpected.
I got the chance to get down there and pre run my section known as the “crossover” from race mile 170 to 240 this past weekend. This is one of the most critical sections of the course due to its remote areas that can leave you stranded for help overnight if you do not prepare for it. The course gets very rocky and technical going over the mountains coming into Rancho El Coyote at race mile 207. The course then heads up the mountains toward the famous “Mike’s Sky Rancho” for more rocky and technical terrain before it drops down to San Matias at race mile 240.
Our plan for this year’s Baja 500 is to navigate through all the obstacles with ease and conserve our Barker’s Exhaust powered Honda Trx450r for 515 miles. In order to win, you must first finish and the team with no issues will take the checkered flag. Not only will this 12+ hour off road race put a true test to man and machine, but will prove that we run the best products in off-road racing. There is no better test than conquering a Baja 500!
One of the biggest challenges Pirruñas Racing will face is racing through temperatures over 100 degrees. Not only will this put a toll on our race quad, but riders will have to make sure they are hydrated while pounding through the 4 feet deep whoops in San Felipe. SCORE is planning to set hydration stations where racers can stop and hydrate if needed without adding to our total race time. Overcoming this challenge will get us to finish line but also prove the athletic capability that racing in Baja takes.
The team and I want to give a special thanks to Barker’s Performance for giving us the confidence in allowing us to put their bulletproof exhaust to the ultimate test. This Baja 500 wouldn’t have been possible without the support of our friends, family, and sponsors who have helped us along our Baja Racing career.

With our recent redevelopment and release of our new Dual Exhaust System for the 2014-2015 Grizzly 700, we have discontinued manufacturing the original Barker's Single Exhaust for the 2014-2015 Grizzly 700. Here's why.
When Yamaha released the 2014 Grizzly 700 with a single exhaust port, we got to work on a single exhaust. At the time this seemed like a natural fit, so we developed, tested, and felt satisfied enough to launch the 2014/2015 Grizzly single exhaust system.
Then when the 2016 Grizzly came out and it struggled on the Dyno a bit, we thought back to the incredible success we had with the 2015+ Raptor 700. This dual exhaust system, which splits into two cans from the single port head, quickly became one of our leading exhaust systems for horsepower gains and overall performance. When we attempted the same style design with the 2016 Grizzly, we were blown away by the gains! At this point we began thinking about the single for the 2014/2015 Grizzly, thinking that maybe we left some ponies on the table with the previous design. We got back to work on the 2014-2015 Grizzly, and sure enough, a powerful dual exhaust for this machine was born.
In our research, we found that these 14/15 Grizzly's run extremely hot from the factory floor. With our single exhaust on this machine, we just did not see the packing life or performance we wanted. After doing some rigorous testing, we found that the AIS system on the Yamaha creates a ton of excess heat. The AIS system adds additional oxygen to the exhaust, causing the exhaust temps on the Grizzly's to get extremely hot. This resulted in the muffler depleting it's packing much quicker than we'd like. In addition to the AIS system, we found that the CVT transmission made the machine run at a higher standard RPM than a geared quad, so the machine coming from the factory already ran lean. Because our duals spread the heat and exhaust flow out and into two separate mufflers, dropping the heat and pressure basically in half, we knew this design would greatly benefit the 14/15 Grizzly.
With our dual exhaust system for the 14/15 Grizzly 700, we also supply 2 pieces of DEI's extreme heat barrier to protect two areas that could be prone to melting plastics. You might also consider greater heat protection to enhance long-term heat protection. For this machine, We highly recommend DEI's Bodywork Protection Kit. To further combat any exhaust heat under your plastics, wrapping the area where the pipes split from 1 to 2 with Exhaust Heat Wrap can further help. We do not recommend wrapping an entire exhaust in heat wrap, though, as this can cause all of the heat to go into the mufflers.
We also do not recommend running this system without properly tuning your machine or adding a fuel controller that is pre-mapped with the ideal settings for this exhaust system upgrade. Blocking off your AIS system can further help to keep the heat down and will prolong the life of your packing.

Barker's Performance is thrilled to announce that Juan Pirrunas Dominquez and his awesome team won this year's San Felipe 250 in the competitive sportsman quad class. Time and time again we continue to be impressed not only by this young man's talent and dedication to racing but also his commitment to his team and sponsors.
We followed up with Juan after his big win at the San Felipe 250 to learn more about the race and how our exhaust performed under such intense pressure. Here's what we learned.
It was another intense San Felipe 250 for Pirruñas Racing. We were very busy the past couple of months in getting physically/mentally ready and in prepping a winning quad. My big brother Alonzo Dominguez and Mechanic Jose Nolasco can take all that credit in prepping us a winning racer! We had no mechanical issues at all. Our Motul Lubricants kept the same oil capacity level all race long and we used the same UNI Air Filter all day. Our Elka Suspension prepped and set up by Felipe Velez at Baja ATV Riders Only never faded away, even after over 250 miles of whoops, rocks, and more whoops! Our Barker’s Exhaust put the power to the ground and kept us in front of the pack all the way to the checkered flag! Like I said before, to be the best you have to run the best and we proved that at the 2017 San Felipe 250.
We drew first off the line out of 8 sportsman ATVs and our goal was to put time on the rest of the competition. So our game plan going into the race was to hold the throttle wide open for as long as we could. The whole team did a fantastic job in following the game plan by finishing over an hour ahead of the next sportsman ATV. However, Sunday we found out that SCORE International provided us with a heartbreaking 1-hour penalty due to missing 6 VCPs that we still don’t know which ones we missed. That gave us a finishing time of 7 hours and 25 minutes and only 7 minutes ahead of 2nd place. Thank god for our Barkers Exhaust!
Pirruñas Racing had a smooth race overall and the course got super rough as we pounded down the 271-mile course. One of our riders was enjoying his ride so much that he missed the first Baja Pits at race mile 41 and handed the quad off to me with an empty tank. We were lucky enough to get some fuel from the 2A team of Don Higbe and Chris Robinson which allowed us to make it to our next fuel stop. I owe you guys some cold Tecates and some tacos! Other than that, we had a flawless 2017 San Felipe 250 and already looking forward to the Baja 500 in June!
The team and I want to give special thanks to Barker’s Performance for giving us the confidence in putting their exhaust on top of the podium. This win wouldn’t have been possible without the support of our friends, family, and sponsors who have helped us along our Baja career.

Imagine navigating through more than 250 miles of tough terrain that's mangled with rocks and sand, and temperatures exceeding 100°F.
Now, imagine conquering all of this in less than 12 hours on the top of a quad. The Score International San Felipe 250 may be the shortest of SCORE's race series, with the Baja 1000 boasting 850 miles of similar off-road conditions, but it is certainly a challenge for many a man and his machine. Attempting to race any machine over 250 miles in under 12 hours with some of the craziest rocky, sandy whoops, and extreme conditions around is no joke. We don't know about you, but it seems like you would have to be one dedicated and skilled individual to take on such a race.
Barker's Performance is proud to have a man such as this on our Sponsored Riders roster. For Juan Dominguez, this will be his 8th time racing the San Felipe 250. We reached out to him to learn more about this year's race and a little more about him and his team. Here's what we learned.
The team and I are getting ready for our 8th San Felipe 250 in a row. The San Felipe 250 is the shortest race of the SCORE International series however, it is the roughest due to its never-ending rocky/sandy whoops. I was down there pre-running this past weekend and the course is already chewed up and temperatures were over 100 degrees! The course will only get rougher in these two weeks leading up to the race.
We will be competing in the competitive sportsman quad class since I had to put a last minute team together. I will be teaming up with a couple guys from our Baja 1000 rival team, Oskar Espinoza and Osman Arce from Ensenada, Baja California. The San Felipe 250 will be starting Saturday, April 1st at sunrise and will have 12 hours to navigate through the rough, 272-mile race course SCORE has put together.
The San Felipe 250 is not new for Pirruñas Racing since it will be our 8th time running it. We have been lucky enough to podium this race about 4 times with one of them being a 1st place finish. We are going to rely on our Barker’s Exhaust to power us through the deep sandy whoops and the never sandy washes San Felipe has to offer. We will be racing a Liberty Motorsports/ Baja ATV Rider’s Only prepped Honda TRX450r.
The team is hungry to win this year’s San Felipe 250. We have been getting ourselves ready mentally and physically the past couple of months and are going for the top spot. We are confident heading into this race since we have a strong group of riders, reliable support crew, and the best sponsors in off-road racing to get us to the finish line on top. But this is Baja, anything can happen at any given time. We are preparing for the worst and expecting the unexpected!
Thanks for all the support Barker's Exhaust!
So there you have it! Stay tuned for more updates on the 2017 San Felipe 250 and the Pirruñas Racing Team! We will add photos and commentary to our blog and social media as it comes across the wire.
We love desert racing!

It's that time of year again. The ATV MX National Championship begins tomorrow and we are beyond excited for this year's competition. Here's why.
What is more exciting than dedicated and skilled ATV racers going head to head race after race for a big win and recognition? Aside from life's greatest milestones, nothing! The ATV MX National Championship is a true test of man and machine, will and skill. We love to see which machines pull ahead of the pack, and how racers handle their machines under tough race conditions.
This year we are especially excited because we have the great pleasure of having two teams running our exhaust this year.
Team Nine6Nine is ready to wage a war this year at the MX National Championship and we are thrilled to have a rider on their team racing with a Barker's Exhaust. Team Nine6Nine member, Alan Myers, #24, will be competing in the Pro Sport/Pro-Am classes on his Suzuki LTR 450. Last year, Myers won the National MX Championship in the 450A class and has since moved up to compete in the Pro-Sport and Pro-Am classes. With Travis Moore to help lead the team to another victory, we are sure Alan and all Team Nine6Nine racers will have a very exciting and fruitful season.
The Harris Motorsports Team is another team participating in the ATV MX National Championship that will be riding with a Barker's Exhaust. Zack Harris will be racing a YFZ 450 in the Pro-Am class.
Be sure to stay tuned and follow along with us throughout the championship. We will be regularly updating our blog and social media with race results and other exciting information. We can't wait to see what's in store for this year's ATV MX National Championship!
Barker's Performance is extremely excited for November 16, 2016. This date marks the start of the 49th Bud Light SCORE Baja 1000 in Ensenada, Baja California, and Mexico. One of the toughest desert challenges out there, the Baja 1000 encompasses more than 850 miles of extreme desert conditions and obstacles. We are super lucky to have one of our very own sponsored rider's participating in the race, Juan Dominguez.
This race will not only be a true test of sheer might and skill for Juan Dominguez and his team, it will also brutally test our exhaust system in extreme desert conditions over a significant amount of time. We look forward to this race and the awesome results we expect both to achieve.
We wanted to reach out to Juan to get his thoughts gearing up for the big race. Here's what we've learned.
How have you been preparing to get ready for this race?
The team and I are very stoked for this years Baja 1000! This year's team consists of myself Juan Dominguez, Julio Banda from Mexicali, Rusty Repass from Maryland, Dan Webb from Virginia, and Alberto Jimenez from Mexicali.
We have been prepping mentally and physically for this race for the last couple of months. Our race quad (100A) was torn down and built from the frame and up. Liberty Motorsports rebuilt our entire motor and of course Barker's Exhaust will keep it running strong for the entire 854 miles! We start our pre-running this weekend so each rider can get to know their sections for when the green flag drops in a couple of weeks.
What are your thoughts heading into the race?
This year's Baja 1000 should be a faster race course then the past years but anything can go wrong in 854 miles of off-road racing. To win you must first finish so preparation is key to get 100A across the finish line. SCORE has set up a very demanding race course with plenty of Baja obstacles to overcome.
What do you think will be your biggest challenge?
I think the biggest challenge in racing Baja is to not have any issues. Since we are racing against time, the less problems you run into the more of a chance you have to win. Our race plan needs to be executed perfectly in order for us to be on the top of the podium. We need to prepare for the worst and expect the best!
We will be posting updates from the big race on the Barker's Exhaust Facebook page so be sure to follow along if you don't already! You might also like to check out the 2016 SCORE Baja 1000 course map.

As the weather warms and you prepare to take to the trails or the track, remember that your ATV will need some love to perform it’s best.
Your ATV needs love all year round, but what you do now to prepare and maintain your ATV will affect it’s performance throughout the entire riding season. Spring is an excellent time to perform a full inspection of your machine to make sure it is in top riding condition and reduce the risk of running into an issue down the road. To help you get the most out of your machine, we’ve put together a list of ATV maintenance tips to help you fully inspect your machine after getting it out of storage.
Inspect Fuel System
- Inspect Gas Tank & Fill Up
- Gas goes bad. Overtime gasoline breaks down and can clog up carburetors or fuel lines. Hopefully, you prepped your machine’s gas tank prior to storage by adding a fuel additive or by draining it completely. Either way, be sure to look at your tank before you decide to ride. Check the tank for any floaters or rust particles. If you find some, drain the tank and thoroughly inspect it. If necessary clean it and refill it with fresh gas.
- Inspect Carburetor
- If your machine has a carburetor it will need to cleaned out from time to time and especially after sitting a while because it can cause build up in the float bowl. Go through and blow out the vent hoses and jets and spray the float bowl with carburetor cleaner. Before re-installing, check the intake boot for any dirt or debris and clean it out.
Check/Change Fluids & Filters
Spring is an excellent time to refresh the fluids in your machine and inspect some of those essential ATV parts affecting the performance of your machine. To get started, drain the existing fluids and inspect it for anything out of the ordinary. Below are a few things you should look for and consider. If you don’t notice anything, replace the fluids and continue on with the rest of your maintenance.
- Check/Change Oil
- The oil is the lifeblood of your machine. Checking and changing your oil regularly is critical to ensuring peak-performance throughout the riding season. Your oil collects dirt, debris, and little metal shavings as you run your machine and your engine wears. It’s good to have your oil changed before storage, but hey, we’re not all perfect. Give your ATV an oil change after storage and give your machine a fresh start to the riding season.
- Check/Change Brake Fluid
- Overtime brake fluid absorbs air and moisture and can get dirty. You should flush and replace your brake fluid if you notice issues with the color or consistency. Low brake fluid is a sign that your rotors may need replacing.
- Check/Change Coolant
- Check the coolant for any signs of dirt and overheating. Coolant that has ran hot for long periods of time will change in color and start to produce a burnt odor. If you notice a milky consistency it is likely that your cooling system has been mixing with your oil system. If this is the case, you may be facing a not-so-fun repair bill. While you’re here check out the radiator and hoses too. A clogged radiator is a big problem so be sure to thoroughly inspect it.
- Check/Change Transmission Fluid
- If there is any project you want to avoid, it’s rebuilding the transmission. Regularly checking and replacing the transmission fluid will help to prevent this costly repair. When you inspect the transmission fluid it should be clear and look fresh. If it’s cloudy or dark in color it’s time to replace it. Low transmission fluid will cause wear and stress on your gears or clutch.
- Replace/Clean Air Filter
- Your machine’s air filter should be checked and maintained regularly throughout the riding season. Neglecting your air filter will ruin your machine as it will suck dirt particles into the engine and wear it out overtime. Prepping your machine after storage is an excellent time to check and clean or replace your air filter. After any day of riding, if you’re dirty, your air filter is likely to be dirty. Clean it up!
Check the tire treads and pressure before hitting the trail. Inspect the tires for any signs of wear or weakness. ATV tires operate at a much lower pressure level than your vehicle’s tires. A tire that loses pressure is a lot more likely to have the bead come off the rim. This causes a lot of wasted time out on the trail or worse, a serious accident. Protect your machine and your life. Check your tires!
Maintaining your ATV’s battery should be addressed before and during the time your machine is in storage. To keep your battery going strong, here are few maintenance tips.
- Remove the battery and clean the positive and negative posts with a mixture of water and baking soda to remove any corrosion.
- Apply waterproof grease or Vaseline to the posts after reconnecting to prevent corrosion.
- Does your battery require topping off? Wear safety gloves and goggles when servicing your battery and only use mineral free or distilled water to top it off.
Spring is an excellent time to inspect your brakes. Do you have disc brakes? Take a look at your brake pads. If you cannot see the indicator marks, it’s time to replace the pads. If you also notice one brake pad having more wear than the others, it is likely your machine needs an alignment.
While you’re inspecting the brakes, be sure to check out the rotors. This would also be a good time to give them a nice scrub as this is a common site where dirt and debris build up. Heck, while you’re at it take a good look at your calipers and wheel bearings too. Check caliper seals and replace them when needed. Bad caliper seals will cause brake dragging or cause brake pressure loss. If you notice brake fluid build up in this area you’re already too late. Lubricating the caliper pins is also a good idea.
Check Front & Rear Differentials, and Suspension
Remember all those gnarly jumps you landed (or didn’t land) last year? How about those darn trees? Did you run into any of those? Now’s the time to check your machine’s toe-in. Start by parking your ATV on a level surface. Check the distance between the center of your right front tire to the center of the front left tire using a tape measure. Then check that measurement at the rear of your machine. Do those numbers compare? Check your ATV’s shop manual to find out what the correct measurements should be, and if you’ve installed an aftermarket front end you will need to check that company’s manual. Check out your suspension. Look for any loose or worn parts - grease if necessary.
Check/Replace Belts, Cables, Chains and Spark Plugs
- Belts become stretched and worn over time so inspecting your ATV’s belts every now and then is a must. If you’ve noticed your machine not shifting as smoothly as it should, there’s a good chance the CV belt needs replacing.
- Inspect your ATV’s cables for any frays or weakness. If you notice any issues replace the cables as soon as possible.
- Do you have a chain-drive ATV? Check the chain for slack and adjust it according to your owner’s manual. Now’s a good time to do a little spring cleaning and scrub your chain and sprockets. A good old fashioned wire brush usually does the trick. While you’re at it inspect the sprocket’s teeth and make sure everything’s intact. Be sure replace any broken or worn sprockets. Once you’ve finished cleaning the chain, lube it up and see if the clutch is adjusted properly.
- Spark Plug
- If you want your ATV to perform it’s best, you have to maintain your spark plug. Your ATV’s fuel-air ratio is affected by the spark that ignites it. Check your plug for any corrosion or wear on its electrodes. If you see any you will definitely want to replace it. Your spark plug is also an indicator of your machine running too rich or lean, which may mean your fuel-air ratio isn't calibrated correctly. If you’ve got more than a full riding season under your belt, you might also want to replace it.
Grease Pivots and Bearings
Getting your ATV out of storage is a great time to get your machine loosened up. Greasing the bearing and pivots is a must. Here is a quick list to help you get your grease on.
- A-arm bushings and bearings
- Axle or carrier bearings
- Front hub bearings
- Pivot Bolt
- Steering stem bushing
Inspect Aftermarket Accessories
- Maintain/Repack Aftermarket Exhaust
- Aftermarket exhausts tend to be internally different from stock exhausts. Most, like Barker’s Exhaust Systems, will require repacking to keep your machine performing it’s best. After a full season of riding you might notice your exhaust getting louder and the can may appear to be getting hot. You may also notice bits being expelled from the rear of the exhaust. These are tell-tell signs that your packing, and potentially your inner core baffle, need to be replaced. Replacing the core packing materials inside will keep your machine sounding and performing as it should.
- How To Repack Your Barker’s Exhaust
- Repacking your Barker’s Exhaust System is a fairly simple task that should be done at least once a year. If you notice your exhaust is louder than usual or the color of your can is discolored, there’s a good chance the packing is too far gone.
- To repack your system, remove the rivets securing the end cap to the exhaust can.
- The inner core baffle should pull away and you can remove the old packing.
- Wrap the new packing around the internal core baffle and secure with the included tape.
- Slide the interior core back inside your exhaust can and secure the end cap.
- Check/Replace Spark Arrestor and Quiet Core
- If you have a spark arrestor or quiet core these will need to be checked for wear and tear and replaced every now and then as well.
- If you ride in sound sensitive areas or areas regulating emissions, you will need to stay on top of checking and replacing these when needed.
- You can purchase a Barker’s Replacement Spark Arrestor or Barker’s Quiet Core for your exhaust on our accessories page.
Check/Tighten Nuts and Bolts
You might be surprised but little things like the nuts and bolts on your machine can cause bigger problems than you may think. Here is a list of nuts and bolts you should be checking after storage and regularly throughout the riding season.
- Axle Nut - loose axles can wear out bearings and could end up wrecking the axle carrier
- Lug Nuts - lug nuts need to be properly torqued at all times, otherwise you could lose a wheel (and possibly a limb of your own) in an accident.
- Pivot Bolts - the pivot bolts hold your machine’s swing arm to its frame. Neglecting the pivot bolts could wear out you machine’s frame and bearings.
- Sprocket Bolts - continuous chain torque from riding your machine will loosen this bolt. Check for tightness regularly.
- Skid Plate Bolts - wear on your skid plate will loosen these bolts so check these bolts to ensure your plate stays in place.
- Wheel Hubs - loose hubs will wear out your ATV’s bearings and could eventually strip axle and hub splines.
Alright! You did it! Your ATV is prepped and ready for your best riding season yet. Make sure your registration is up to date and LET HER RIP!
If you’ve been following Barker’s Exhaust for the last year, you’ve probably noticed Juan Pirruñas Dominguez and the Pirruñas Racing Team. Juan partnered with Barker’s Performance as a sponsored rider in February 2015 and has since made quite an impression on us and the desert racing industry.

This year we watched as Juan and the Pirruñas Racing Team endured rigorous racing schedules and dominated extreme desert racing conditions. Because of Juan’s commitment to running our exhaust system on his machine, we have had the tremendous opportunity to learn more about desert racing and how our exhaust system performs under these conditions. We thank Juan and the Pirruñas Racing team for their continued dedication and support and we look forward to another year of outstanding performance!
Sponsored Rider Interview
We wanted to get to know Juan better and thought you might want to too, so we reached out to ask him a few questions about himself and the Pirruñas Racing Team. Here’s what he had to say:
Q. Juan, you seem to be incredibly dedicated to racing. Can you tell us a little about your roots and how you got started in desert racing?
I got my first quad when I was 14 years old and my whole family was always into off-road racing and going to the dunes on the weekends. Since we live in the Sonoran Desert, I started to love riding out in the beautiful desert scenery that Yuma has to offer. After watching the documentary of the Baja 1000 " Dust to Glory," I saw there were quads participating and that's where my dream begun. I decided to attend the Baja 500 when I was 16 years old and absolutely got hooked on the Baja racing atmosphere!
Q. Clearly the Pirruñas Racing Team plays a big role in your racing career, can you tell us a little more about your team?
Pirruñas Racing started back in 2008 when we did our first ever CODE Offroad race right across the border in San Luis, Sonora. We raced a stock Raptor 660r and placed 7th out about 25 quads. The team consists of my brother and I who are trying to follow the same dream in being champions and maybe one day pick up a Honda Factory ride. In Desert racing, without a support team you are nothing out there, so I am blessed enough to have family and friends come out and help us out in different sections of the course and help us get the quad to the finish. As a matter of fact, the name Pirruñas came from my nickname and it’s a pretty noticeable name in Mexico.
Q. In 2015 you raced some pretty intense courses, can you tell us a bit about your experiences riding in desert races like the SCORE international series?
2015 was a great year for us! We won every single race in the SCORE series and to be honest it is not an easy task to accomplish. Those races are hard enough just making it to the finish line. Preparation is the key to get to the checkered flag and running durable products on your race quad such as Barker’s Exhaust is another factor in getting to the finish. The terrain is tough enough on your machine and a bit worse on your body so you have to be in top physical shape to be competitive. In order to win you must first finish so you just have to trust in your other co-riders and ride at a smooth fast pace.
Q. We understand that a ton of thought, modification, and maintenance goes into making a machine, and a man, race ready. Can you share a little bit about how you get yourself and your machine ready for a race?
As we all know Desert Racing is a true test for man and machine so preparation is the difference between winning and losing. We start prepping for our next race as soon as we cross the finish line of our last race. After every race, we sit down and write notes on what went wrong and how we can improve. Being in top physical riding shape is a priority for every rider in the team so that means a lot of blood, sweat, and tears in the gym as well as getting as much seat time as we can before the next race. As for the race quad, we tear it down all the way to the frame as well as the motor. Although Honda is known for their reliability, we tear the motor down and replace everything that is necessary to get us to the finish line for the next race. The only part we re-use on our quads is our Barker’s Exhaust. We put thousands of miles on them and they still retain their race condition. Most durable exhaust on the market in my book!
Q. It looks like 2016 is shaping up to be another big year for you and the Pirruñas Racing Team! Can you tell us about what this year has in store for you and what you are most looking forward to for this year?
After winning a championship in the SCORE International Series and in the CODE Offroad Series in 2015, we are setting sights in winning the SCORE International Pro Open Quad Class for 2016 and make our dream come true in running the 1A plate for 2017. Tons of money, time, and sweat will go into this goal but we have the team and sponsors to make it happen! One change that we'll be doing this year is that my brother Alonzo Dominguez will be focusing on prepping our race quads and pre-run quads instead of riding and being a mechanic at the same time. This will allow me to focus on logistics for the races and be a more competitive rider for the Pro Class. We also have a new team of riders for 2016 and they consist of myself; Gilberto Ramirez from Phoenix, AZ; Julio Banda Jr. from Mexicali, Baja California; Jose “Moño” Contreras from Tecate, Baja California; and Jorge “Wero” Contreras from Tijuana, Baja California. All these guys have what it takes to accomplish our goal in being Open Quad Pro champs for 2016! The whole team can’t thank Barker’s Exhaust enough for their durable exhaust systems and allowing us to come out on top!

The Barker's YFZ systems come in many shapes and sizes to work with the many variations Yamaha has developed over the years. There's the YFZ450 Single Exhaust System designed for 2004-2009 and 2012+ Carbureted models. There's also the YFZ450R Single Exhaust System designed for 2009+ EFI models. Also, if you're not quite ready for a full system, we offer a Slip On YFZ450 Exhaust that fits all year models, carb'd or EFI. Finally, if you have a modified system designed specifically for drag racing, we've got a YFZ450 Drag System.
With all the variations and changes over the years to the YFZ 450 machines it can be confusing choosing the proper system for your machine. A lot of people were thrown for a loop when Yamaha went back to a carbureted system in 2012 and you'll find there isn't much information out there from exhaust companies. Luckily, Barker's customer Nate owns a 2012 Yamaha YFZ 450 carbureted model, and through working with him we've verified that our single exhaust for carbureted systems works with these newer carb'd models! Nate informed us that after installing the Barker's exhaust his 2012 Carb'd Yamaha YFZ 450 came to life. If you have this rare carb'd machine and want customize it, our exhaust system is the perfect upgrade.
Customers love these systems. Tim from Pennsylvania rides a 2014 YFZ 450R outfitted with our single exhaust. Tim says, "I just wanted to say that I am really happy with the power gains I received throughout the powerband. Also I really like the craftsmanship you guys put into your pipes." Tim sent us the photo below of his machine with his new Barker's Exhaust.
Local customer Doug Booms also sent some photos of his Yamaha YFZ 450 outfitted with the Barker's Exhaust:
