This is the second Pro Circuit Pipe I have installed on my last two bikes. The first was a Works Pipe on a CR500. My current KTM 300 XCW, runs great with this pipe! Top end pull is better than the stock pipe, which I think may be made for KTM by FMF. Installation was approximately ten minutes and the fit was better than new! I recommend anyone looking for a great looking pipe that delivers the power to look at Pro Circuit. Have a great ride!
