WOW!! This exhaust makes my 2010 KTM 250 XCF-W run much better. More power at low and mid RPM and gains RPM's much quicker. The FMF muffler is 1 lb 3 oz lighter than the stock muffler. I borrowed a decible meter, stock muffler is 96-97 db, FMF is 98-99 db. The FMF is louder and has a much lower tone. It seems to make my bike run a bit hotter. Suggestion for RM ATV/MC: Change the picture on your website from a blue muffler to a silver muffler. FMF does make a blue anodized muffler. I thought I was getting/buying a blue muffler but RM ATV only carries the silver. No big deal as the silver looks fine, just a bit deceiving.Read All Reviews

Ok so this slip on was simple to install, just had to read the picture and make sure all the little washers and adapters were in the correct spot. But the best part. this machine sounds like it has some nuts now! I am very impressed with the look and sound of this slip on. I am very excited to see if there is any noticeable improvements with performance. For the sound, I personally do not like the annoying loud sound of aftermarket exhausts, so this Yosh is perfect for me. Deep throatie sound and shaves a couple pounds off the machine!Read All Reviews
