FMF 4.1 for KTM 250

Comments On Jun 26, 2012: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.

A big bang for the buck

Comments On Oct 24, 2007:A great exhaust, I noticed a huge gain in low and mid range power. The weight savings compared to the stock pipe was a big plus. Fully satisfied.
