Its a long bumpy road trying to find the perfect pipe for your bike. Some are too quiet, some are rip your face off loud.... Others can sound like a bad day in the office restroom. This FMF powercore IV S/A Silencer hits that sweet spot... The exhaust note this baby puts out will have you twisting throttle more and making excuse to the wife just go hear it idle. I loved my FMF slip on, The Quality and fitment were spot on! clamps fit well and nothing ever loosened up on me. I got real cray and removed the S/A and threw on a FMF Powerbomb head pipe. the Sounds my machine produced were mind blowing. pretty much the greatest thing these ears have ever heard. Support FMF support RMATV and DO NOT HESITATE to order this slip on.Read All Reviews

Really happy with this system. Replaced my toasted Yoshimura silencer with the DRD and couldn't be happier. I don't feel that my 450 needed or needs more power but the DRD did smooth out the delivery and gave the bike pretty good snap off the bottom. Would certainly consider DRD again!Read All Reviews

The FMF 4.1 aluminum exhaust system fit perfectly, looks excellent, and it sounds great. Along with an ECU remap, it certainly gave the bike more power, and deleting the left muffler probably helped a bit too. The UFO side panel fits perfectly as well and the bike looks as though it came from the factory with single exhaust now.Read All Reviews
