    Does anybody know if the WR250-Gnarly works on the 300?
    Or were I can buy one for the 300?
    FMF has no Gnarly for WR300 in the application chart.:excuseme:

    Nothing from what I hear but the FMF looks a lot better.

    Tisk tisk. Looks should never trump function John. I've actually had 2 people tell us the DEP exhaust on our '09 KTM 150 SX looks "retarded". But it screams. And the power is obvious.

    The FMF pipes are the same stamping for the 125 and 150 (144) KTM. DEP manufactures their pipes based on dyno tests performed on the specific motor. Hence different shapes for different applications.

    You can buy "hype and looks" or you can buy function. My money is on function.

    I have heard that the "best" pipe for a WR300 is the stock WR250 pipe.

    And the best pipe I have tried for the WR250 is a 2C. Have no idea how to get one but they RIP with this pipe. Noticeable over stock. The PC pipe kinda sucked IMHO. Made it soft.

    I'm playing Devil's advocate here... but why on Earth would Husky go to the trouble of engineering a different pipe for the 300 if the stock 250 pipe was "better"?

    Again, Scott, not trying to start a $hit flinging contest. But I'm skeptical. My WR300 was a MONSTER with the '09 stock exhaust. The '09 exhausts are different between the 250 and 300. Maybe for a reason? The '10 300 exhaust is supposed to be even better (even more different than the 250? :excuseme:).

    It'd be really nice to see dyno curves on both exhausts. :thumbsup:

    I installed a FMF Fatty on my 08 CR and it out performs my stocker. And it looks better!
