First here's the set-up: Car--96 civic coupe Motor--B18b Okay, here's the deal...Its a b18b with stock header, My EX cat and a tanabe Racing Medalion. I have an RS*R ex-mag in the mail and my current set-up is ghetto rigged, has a huge leak, sounds like crap and looks like crap. When my RS*R comes in, I want to do it the right way. I've decided to remove the cat in favor or a Test-pipe, but I really don't know if anyone makes them, what length I should get or if I can get one for a 99-00 Si and will my exhaust made for an EX still bolt up? I've talked to some local shops and they said they could weld a test pipe in, but if I can find one, I'll just buy that and put it in. Any help here..what are you gusy using? Cliff notes: EK with an LS swap, what cat/Test pipe should I use to make it work with an exhaust made for a 96 EX?
