SideWinderGX · 02-28-2007, 05:25 AM

im just gonna do the exhaust myself because a) im a cheapo, and b) i want to actually do some stuff on my own car...learn how things coexist within the car and help it to run, and learn how to fix everything myself. but ok, thanks for the other info....prolly bolting it on because i have to take it off eventually to put on a new 3" downpipe anyways, its got a crack in it.

I think emission laws really depend on what state you live in. But I think universally removing ANY catalytic converter is technically against the law. Replacing them with a high flow is not. Find out if your emissions testing place even checks for that stuff. In my state, at least my town, they didn't even check the exhaust system, they just put the hose in the tailpipe, and plugged into my lighter socket and had me run it to 25mph for a few seconds to get a reading.

One thing I noticed you didn't have listed (or I didn't see) was an aftermarket exhaust header. I don't know if it's needed or not, but you might check into it. Couldn't find one on suprasport other than the N/A ones, but I'm pretty sure they make em.
