The Yamaha YFZ450R Fuel Customs Big 3 Package with Power Commander 6 and Fuel Customs Intake is a game changer when it comes to increased performance for your machine. 



Our YFZ450 Pipe is truly one of our top performing performance pipes. We've heard over and over how shocked our customers are with the "true" horsepower gains that come from this pipe. Many squash or dent their pipe where it goes through the subframe, for ours, we sneak right through the tight fit leaving a perfect flowing pipe.

We consistently design our systems using the Reverse Megaphone technology and this is a machine that truly utilizes it. The YFZ450R is a perfect fit for a stepped reverse megaphone pipe that is designed to hold up extremely well. Quad's aren't like MX bikes where many competitors are striving to make the thinnest, lightest pipe possible. ATV riders need top notch performance but don't want to be replacing cracked pipes or re-packing after every race. Most of our competition uses .031 wall Stainless Tubing compared to our .049 wall 304SS Tubing. Titanium is cool and light but the durability in a rough ATV race is just not there.

We carefully hand tig weld a 40% thicker pipe than most which makes for an extremely durable race-proven pipe that not only performs beautifully, it holds up under the most extreme conditions found in some of the most whooped out MX Tracks on the National ATV MX scene. We built this pipe to last and with our muffler being mounted with a Solid Billet Bracket (no welded on tabs), and also packed it with the some of the best materials available, so our exhaust won't be outdone by the competition.

Just recently, with the help of our friend Jim Hardy a 20+ year ATV Racer, we got our hands on a literally brand spanking new 2018 YFZ450R. We wanted to show exactly what you're looking at if you take a bone stock YFZ450R and added our Pipe, Fuel Customs Intake, and a Fully Mapped Power Commander 5. We are very pleased with a solid 5hp peak gain over stock, and a ton more in the over-rev, giving you a ton more power before you rev-out. As you can see on the dyno chart below, gaining over 8hp at 9,500 RPMs.

Further gains on built motors are even broader in many cases. We've seen this pipe perform extremely well on Motors nearing that 60hp mark. If your just a trail rider looking for a quality performance pipe or a full blown ATV MX Racer looking for top durability and performance we truly think you'll be very pleased with our YFZ450 pipe. 


The Fuel Customs Big 3 Package for the YFZ450R is a game changer when it comes to performance and power production. We designed our Full Single Exhaust System with racers in mind since this machine is a proven winner at the track. After much research, development, and testing we were able to build a full single exhaust that achieved greater power and better performance over the stock system. Now that we've had our Full Single Exhaust for the YFZ450R in production for a few years, we've been able to play around with different fuel controllers and intakes to see if we could further unleash the machine and improve performance. 

The Fuel Customs Big 3 Package with PC6 and Fuel Customs Intake System with Barker's Full Single Exhaust was able to create even more horsepower, torque, and throttle response. We are very pleased with a solid 5hp peak gain over stock, and a ton more in the over-rev, giving you a ton more power before you rev-out. As you can see on the dyno chart below, gaining over 8hp at 9,500 RPMs.

Barker's Exhaust, PC5 Mapped, FCI Intake for 09+ YFZ450R


Each and every Barker's Exhaust System is manufactured from premium materials that are hand welded in the USA. When most other after exhaust systems are mass produced, Barker's Systems must be skillfully hand welded one-by-one. The exhaust pipe portion of your new system is made from 304 stainless steel that is Tig-welded with seam-reduced surfaces for smooth flow. The can is comprised of 6061-grade aircraft aluminum and comes standard in a brushed aluminum finish. You may also choose to have your can tips powder-coated in a black, blue, or red finish for added character. Finish off your new system by selecting which color Barker's Tag you would like. You can choose black, blue, red or yellow.

Other options to consider include the Barker's Quiet Core Insert and Spark Arrestor. The Barker's Quiet Core Insert is ideal when riding in those sound sensitive areas and can reduce sound by up to 5 dB. With only a loss of .5 to 1.5 horsepower, you may decide to ride with it in all of the time. The Barker's Spark Arrestor will prevent flammable debris from being distributed from your exhaust and will help keep our trails safe.

At Barker's, we have an extreme amount of dedication and respect for the off-road lifestyle. And we understand that owning and maintaining a performance vehicle is no joke. That is why you can expect only the best in Barker's craftsmanship and design. All Barker’s exhaust systems carry a limited one-year warranty against defects in workmanship and/or materials. See Barker's Terms & Conditions.


We recommend that you monitor and check the packing in your muffler after every ride. The length and time your packing will last will vary depending on how and where you ride. When you first notice any sign of the packing depleting within the can, it's time for a repack. Packing will wear out slowly over time, starting at 100% packed. It is normal for an absorption style high-performance muffler to lose packing but once you lose more than about 10-15% of your packing it will deplete faster and faster since it can now move around in the can. It is imperative you do not allow the packing to deplete too far. If your muffler becomes very loud or you hear rattling around inside the can you have completely depleted the internal packing and should not ride the machine until the muffler is repacked with a fresh pillow. Order new packing before you need it!

The Barker's Exhaust Complete Repack Kit is designed to make repacking your Barker's Exhaust Can simple.
