    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.

    Well worth it

    First off I love ordering from Rocky Mountain MC. I ordered the pipe Friday night and it was on my door step Saturday morning, standard shipping is always lightning quick as I live in idaho and they always ship products immediately. As for the pipe, I bought it to replace my pro circuit forest service approved pipe. All in all it's 1000 times better. It's still pretty quite, I believe it has a spark arrestor as well, has a deep throaty sound that is music to any two stroke lovers ears, and best of all it wakes up the power band a bit. The pro circuit platinum 2 pipe with this silencer is a deadly combination that I'll use for a long time.

    Sounds Great

    I'm very happy with this product. It sounds great, a lot more tamed than the stock exhaust.
