Hey, don't know much about banshee mods, pipes in general, but i know the Toomey T5s are good if not the best, and CPI's are pretty good too. I know a lot of brand names, possibly them all except the people who make the 2 into 1 pipe but i wouldnt be interested in that anyway. As far as Pro circuits and Bill's pipes and Paul Turner's i don't know how they compare. I would be looking for a pipe with real good acceleration,top end i'm not too concerned about, all though it doesnt go un-noticed, but i would be more interested in arm wrenching power from the second ur on the gas. Well please let me know what you know, thanks.
