I am thinking of buying a PC T-4 for my XR600. I know they are loud but how is the performance and can you quite them down anyway. It has the 2" tip and a spark arrestor screen which I guess you can remove?

I had a T-4 on my KTM and for the most part I liked it. the pipe is light and did provide extra performance over stock. the spark screen was removable, and the end caps are interchangeable to help tune power. I think they sell an insert that helps quiet down the pipe, but I am not sure. I ended up trading the pipe for a stock unit because it was too loud for those long rides.
