    Awesome silencer

    Super quiet made power delivery smoother and definitely an increase in power in bottom to mid range. Only negative is it is a lot bigger than other silencers but I love it

    Grippin n rippin

    By far best value for what you get. Improved performance all around especially pairing with the fmf gold series gnarly woods pipe. Less than 5 minute install. Sounds and looks great and came to my door as expected. No disappointments here ! Thanks Rocky Mountain atv/mc !!!

    Excellent

    No problems, paired with Pro Circuit Platinum 2, it's a pretty tight squeeze but it works. Good power. Hasn't choked down the bike that I can tell.

    Great fit and doesn't affect power

    I installed this for trips to to Utah and Colorado where a spark arrestor/silencer are required. It fits great and doesn't affect power and did not need to rejet.

    A not-so-good fit

    Just installed this on my 2014 300 xc-w. I would love to give it five stars, having spent as much as I did on it, but I can't. The fit isn't perfect as I pair it to the stock header pipe. I had to tweak it, putting unwanted pressure on the header a certain way. It took the force of the two mounting bolts to get it in position. In other words, I couldn't just hold it in its proper position. I had to put pressure on it with one hand and use the other hand to get the bolts in straight. I would like to think fmf could be closer on their specs than that. Maybe the pipe will fit better to an fmf header - I don't know - but I'm not real happy with the way it fits to the stock.
