Great product !

I bought this a couple of weeks ago and have only rode the bike one time with it but has made a change defiantly on the lower to mid power. I would recommend this pipe for any 2-stroke application it does what it says it will.

Nice pipe

The pipe fit on my bike perfectly and lined up with the existing fmf powercore 2 silencer . I noticed power gains all through the RPM range and I pulled Wheelie in every gear .

FMF Bombtrack!

Roll these pipe on every dirt bike I've had. Can't wait to buy more. Usually run the gnarly,but this time went fatty style. Pipe makes the bike really crisp. Reccomend sealing pipe at cylinder with liquid gasket, as
in the instructions on yz's. Couldn't be happier!

Sounds good, haven’t ridden yet.

Great looking parts, only issue I came across was the washers and spacers for the silencer didn’t line up the best. Didn’t give the best instructions on which size spacer went where.

Great replacement for 2015 stock 300XC pipe

Great replacement for 2015 stock 300XC pipe. Great fit and comes with o-rings. Power delivery feels same as stock pipe. CF pipe guard that had been on the stock pipe fits tis one well also.

A: These pipes don’t use clamps, the pipe slips inside the silencer and then they have a rubber groment that goes over that joint that seal it.

Q: Does this include just the pipe and not a muffler?
Over 8 months ago
I Have a 2000 Polaris Scrambler 400 4X4, and I was wondering if there was a pipe and muffler combo for my Quad. Does this pipe include a muffler, if not, where can I find one that fits my Quad?

A: This is only for the pipe. Unfortunately we don't offer a muffler and pipe combo for your ATV.

Q: Just got a 2006 yz125 and was wondering if this smoothens out the power band enough to notice a difference. Right now it feels like a slingshot.

A: This will give you more bottom end. You might need to re-jet your carbs to smooth out the power band.

A: Yes it will! You will have to profile a 2014 250xc to get it to pop up though. The only difference is the exc has a headlight. both 2 stroke.
