  • FMF Factory-4.1 RCT Aluminum Silencer with Stainless Steel End Cap

    FMF Factory-4.1 RCT Aluminum Silencer with Stainless Steel End Cap

    Ryne in AZ

    Perfect

    Lined up perfectly with stock header and subframe. Came with a lower mount bolt, spark arrester, and wash plug. Have several ride on it and it definitely woke up the CRF a bit. Was hit directly on the muffler by another rider and other than some tire marks there was no damage. Can take some abuse. Not sure why the SS version doesn't come with the ufo single side panel.

  • FMF Titanium Powercore/PowerCore 4/Q4 Quiet Core Spark Arrestor

    FMF Titanium Powercore/PowerCore 4/Q4 Quiet Core Spark Arrestor

    Samuel in MS

    good product, bad install.

    This quiet insert does exactly that, it reduces the bark of the exhaust to a reasonable level. My only complaint was with the install, wrestled with the screw for about an hour and ended up having to deburr the hole and use the old screw instead.

    Sounds Great

    I'm very happy with this product. It sounds great, a lot more tamed than the stock exhaust.

  • FMF Pipe Spring & O-Ring Kit

    FMF Pipe Spring & O-Ring Kit

    Stephen in CA

    Good alternative to OE.

    I am not sure how much the OE springs and seals cost. But these do work well. I like that the springs in the FMF kit are black because it matches my color scheme. O-rings seem to be good qaulity. No leaking so far. I have about 15 hours on them. Only thing I noticed is the spring pressure is less than the OE springs. Does not affect pipe fit or retention.

  • FMF 2-Stroke Silencer Packing

    FMF 2-Stroke Silencer Packing

    Stephen in CA

    So far it has not blown out!

    Good price. Good product. Could use a little more in the package, my turbine core 2 silencer could have been packed a little tighter... But other than that it has held up well. Have about 15 hours on it and it is holding up well thus far!
