Mark and I are gonna try and gut it tonight... if I hate it I will immediately buy the BAT Hi-flow dealio..
I'm assuming that the damned car will be in the shop for quite some time anyways - I just want to get it unclogged ASAP so I can go back to driving it and not worry that the blasted thing will start on fire or something because its smoking and physically hot to the touch.

I think I might have a stock Y-pipe and flex area at home too (buried somewhere though)
WTF is a test pipe?
