Excellent exhaust system. Installed on my 2004 Honda CRF150F to replace a uncorked stock system that was on the bike when I bought it. I bet this exhaust saved over 5lbs than the factory system. And it looks and sounds great! Thank you Pro Circuit and Rocky Mountain ATV MC.Read All Reviews

I would recommend this product. I installed it on my new KLR 650 and it brings a much needed sound and didn’t need to mess with changing out jets. The most novice person on the planet could install it in minutesRead All Reviews
