Ok i live in Miami, and in Florida period there are no smog tests/emissions checks... So i was thinking that a cheap mod for right now could be to flush out my stock cat. or even eliminate it. I know i could easily get an aftermarket 3 " exhaust done. But i just wanted to try it out, since my buddy works at a muffler shop and he's done it to a few other turbo cars, mostly DSM's.. Only problem i can think of right away is a CEL, but i think it can be fixed with an o2 sim. from casper electronics.
