BARKER'S ENGINEER COMMENTS
Our Performance Exhaust Complete Package is easy to assemble and install, just take care to not touch the pipe when removing it from the box or during installation. We highly recommend wearing clean white cotton gloves as the oils from your hands will tarnish the sandblast. This can only be fixed by sandblasting the head pipe again. The sandblast on the head pipe will change in color as you put more hours on your new system, and over time will better match the stock header on your machine.
DESCRIPTION
Our Slip-On Exhaust System is a perfect fit for your Buell 1125R/CR! This system consistently gets rave reviews from fans for the amazing sound and the very noticeable 14-pound weight reduction. One reviewer especially commented on how this system "felt like riding a tiger...it just growls." Our Buell 1125R exhaust system was also part of a fully independent shootout that produced some pretty impressive Dyno results.
A popular question from Buell 1125R riders shopping for an exhaust system is the noise level. While those in forums have stated the Barker's system on their Buell is pretty loud, the audio data really speaks for itself. The stock system features a range of 88-99 dBA from idle to 5000RPM. The Barker's exhaust system is 98.2-107.9 dBA for the same range. Almost all of the competing exhaust systems on the market measured a higher decibel reading than the Barker's system, though our system does add a bigger sound over the stock. Of course, we offer a quiet core to reduce the noise level should you desire one.
You can choose to install our 1-1/2" Quiet Core or our 1" Quiet Core for the Buell 1125R/CR exhaust. The 1-1/2" Quiet Core is good for all around use, and the 1" Quiet Core is better suited if you need to quiet down the system. As the 1" Quiet Core quiets the exhaust down more effectively, it does result in a slight loss in power.
What about torque? The Barker's exhaust system also improved peak torque when measured by an independent testing facility. With the stock system holding at 70.24 lb-ft, our system peaked at 82.68 on the race map.
The Buell 1125R slip on exhaust is constructed of 304 stainless steel that is tig welded with seam-reduced interior surfaces for smooth flow. The reverse-cone megaphone with pulse-wave tuning technology offers superior peak horsepower, enhanced over-rev, and improvements throughout the rev range. Consider adding the quiet core to reduce the sound level, but note that the use of the quiet core will reduce some of the horsepower gain, typically 1.5 HP. This system also features an option for ceramic coating on the pipe. The ceramic coating should be added to the cart separately if you would like your pipes coated.
Are you a data junkie? This system offers a multitude of independent data compiled by AmericanSportBike.com including sound bites, Dyno runs, and an extensive writeup about all of the exhaust systems they tested. The write-up offers extensive information about many different systems available for your Buell 1125R and you can easily compare ours to others on the market.

MAINTENANCE:
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.
