RE: First Post...Have exhaust questions?
what ryan said.
It's illegal on a federal level. You just won't get caught if there's no testing. But a cop COULD still look and see if it's under there. It would have to be a real prick cop though, and he'd have to know your car. How many cops out there are going to suspect a mark 8 of running without cats?
I suggest headers. When i had my mark 8, i had long tubes and a full exhaust on it. I don't talk too much about the cat situation. I'm not too big on admitting to things that I "might" have done that "might" not be entirely legal, online.
Welcome!
