a nice stock cylinder 4 mil will be very impressive. Call Cam @ redline racing. He would have my vote to hook you up for a NASTY pump fuel 4 mil setup. I think it'll be everything you want and more! Pipes are personal prefference, I run shearer pipes but i like CPI's just the same, they both make great power! Hard to go wrong, talk to your builder you select and see which pipe they would recommend!
Edit:::
Oh and be ready to spend some money...this build will NOT come cheap. While its torn down, you should also talk to cam about "pro modding" your trans. Camatv here on the hq did mine, looooove it.
