With a stock exhaust setup except for flowmasters that is, what headers would give me the most performance, and shorty or long tubes? and should i just go 2 and a half inch pipe with only 2 cats(not sure how many i need to be able to pass smog, have 4 of em now heh) anyways help would be appreciated. And also I want to cut the pipes after the muffler and drop it before the rear wheels, would it make it sound a lot louder or should I not even bother with it?
I think even a stock engine is happy to be able to breathe a little!
