Headed to glamis this weekend. I havent had much play time on my cr500af 2001. It has the Eric Gorr "all over" porting.

Curently has the Gnarly on it, but I have a pro circuit sitting in the garage. What differences could I expect?

I have heard the PC is mor for top end. How much more? 200 RPM 500, 1000 ????

I had a FMF Gnarly when I got my bike, so that was all I knew. It got dented up and I replaced it with a PC works pipe. WOW!! I like it better! Before with my FMF it seemed like it would never reach peak RPM (mabey it was all the dents).
I don't know? Seems like every time I change anything. I'm like "WOW!"
Just moved my bars Forward with an adjustable top clamp and I'm like "WOW" now I can ride FASTER and feels BETTER! Starting to think that it's all in my head. The grass is allways GREENER

either one will work fine. from those 2 options i also like the PC better though.
