    Pro Circuit T-4 S/A Complete Exhaust System

    Great Product to install on your bike.

    Bought this for my wife's bike and it woke it up. Noticed better power throughout the range. It allowed her to pull the hills better. I was impressed with the noise level. Sounds great without making is loud. Would buy again anytime. Well worth the money for a mod to increase power.

  • Pro Circuit Platinum 2 Pipe

    Pro Circuit Platinum 2 Pipe

    NEIL in AZ

    Excellent choice!

    Changed from a FMF to the PC pipe. Much higher quality built right off the bat. Very smooth low end torque with a improved punch in the mid to full throttle conditions. Great choice and improvement. Very happy with the fit and quality of all PC products.

  • Pro Circuit Factory Sound 304 Silencer

    Pro Circuit Factory Sound 304 Silencer

    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.

    Ethan in AZ

    Great Low End Snap

    I have these silencers for both my CR250s (03,07) they provide more low end snap than the standard fmf silencers I was using with no discernible loss in top end power they also sound great giving you that nice sounding bark of a 250 smoker an added plus is they also look great.

    Quality piece

    Getting this installed soon, but my initial impression is that it is very well designed, and looks strong.
