    Can't tell any difference

    I can't honestly tell if this made any difference to my power curve whatsoever. I don't think that I would recommend it.

    would have went with JD

    this kit works alright, but to me its just a dyno jet set with FMF stickers. I ended up changing out needles and different mains anyhow. this kit also doesn't come with any pilot jets, that would have been nice to know.

  • FMF Q4 S/A Silencer

    FMF Q4 S/A Silencer

    Good pipe, fit perfect

    The FMF Q is a big improvement over stock; it's quieter and provides better low-mid hit. The Q is quite a bit longer than stock so the bike has a different look, but the pipe is a nice addition. I'm rating the pipe with a 4 because I was expecting / hoping it'd be more quiet than it is - that being said it is more quiet than stock and has a better overall sound (deeper). I was also expecting a bigger power gain than I felt. All the threads on 2008-2009 YZ450F's say that any aftermarket pipe will add 5 horses, I'm not sure the Q gives that much of a boost. With the Q and a 165 main jet I was better able to wheelie through the deep sandy whoops (4th gear). I also have some peace of mind knowing my pipe is now compliant to state and federal laws regarding noise and spark arrests. Install was easy, I didn't need either of the 2 inserts it came with. The Q simply fit over my header. I used high temp silicon (gasket maker would also work) to seal the 2 pipes together (as listed in the instructions). Install was 15 min. including the time finding my silicon.

  • 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.
