I have a 2001 400 EX and just got my Pro Circuit T4 slip on and it went right on, but I was wondering something. Do I need to use the stock exhaust clamp or not? It doesn't seem as though it would fit very well if I do, but I'm sure I could get it on there if I had to. The T4 has an o-ring inside which made a leak proof seal. I can't hear any leaks or anything, but didn't want to screw anything up. So, do i need a clamp or not?
