    FMF has made it clear that we love 2-strokes, and they're backing it up by adding an all-new muffler design to their line-up. Don Emler headed up the Q-Stealth personally, because he loves to ride 2-strokes and is dedicated to reducing noise levels. The Q-Stealth is living proof FMF is the only exhaust company committed to bringing new technology to the 2-stroke enthusiast.
  • Quiet on the trail as well as on the sound meter.
  • No power loss.
  • More packing volume-longer time between repacks.
  • USFS approved spark arrestor.
  • AMA and FIM enduro legal.

Super quiet and tough.

Comments On Jan 22, 2014:The Q-Stealth is a really good silencer. It has held up really well and after a year I went to put new packing in and it still looked pretty good. It's very easy to work on and super quiet.

Stealthy and a value

Comments On Aug 13, 2013:Excellent fitment, a little less sound, lower in tone, further between packing. I think they're a great value because it's hard to put a price on keeping riding areas open.

Big, bulky, heavy, poor fit.

Comments On Jul 06, 2013:I was barely able to mount mine up without moving the mounts. They are off about 6mm.

Very nice silencer

Comments On Apr 22, 2012:FMF makes top quality stuff. This silencer, though bulky and a little heavier than the shorty it replaced is thankfully a little quieter, (we can't make our bikes quiet enough these days) and the fit and finish as with all FMF stuff is great. Only thing is, on a YZ250 and probably most other Jap 2 strokes, is the amount of noise coming from the motor and expansion chamber is MUCH more obvious and pronounced after installing this silencer. Wish the YZ engine area could be as quiet as say, a 200xc.

Perfect fit - no power loss - quieter than stock

Comments On Sep 28, 2011:It is a perfect fit on my 2011 YZ250 with no discernible power loss and it is a lot quieter. Why don't they come stock with these? Oh, I know, because some of you guys need the manly noise!

Really quieted my YZ250

Comments On May 15, 2011:The fitment on my 2007 YZ250 was perfect. It is much quieter than stock - when standing next to the bike intake noise and the expansion chamber really stand out. On the trail your buds will be looking back to see if you're still there.
