  • FMF Gold Series Pipe, "Gnarly Torque"

    FMF Gold Series Pipe, "Gnarly Torque"

    keith in MT

    Great clean power delivery

    Much better than the new ripple design thin wall ktm pipe. The stock pipe got bent on the first ride. The Gnarly is 18 gauge steel and much stronger. I has smooth power delivery in all rpm ranges. Works Great right off idle on steep technical switch backs. Does not hit hard and do Vigilant wheelies like some pipes.

  • FMF Power Core II Shorty Silencer

    FMF Power Core II Shorty Silencer

    Moses in CA

    A little damaged but works

    I give it a 4 star cause when I got the exhaust with the factory pipe, first I put the 2 together and they didn’t fit.The tube was bent so i wedged a something millimeter tool and hammered it so it will be round so that I can put the pipe together. After that it worked like any other fmf pipe would. BRAPPP!!! Increase in torque in the low end forsure. If your getting a lot of air out you gotta get a lot of air in. So installed a K&N filter as well. Sounds and feels much better than stock.
