THE FULL STORY:
Our Buell 1125R slip on exhaust system is certainly one for the books! 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.
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.
