So I have an exhaust leak where my pipe rusted off the resonator. So I'm looking to get a 3" cat back with a new down pipe. So I'll be running one cat since I can't seem to find a down pipe with a cat inside.
Anyhow, my question is will I need a tune after a new bigger exhaust system? A buddy of mine is saying since I will have more air flow I will probably need a tune for more fuel fixture. I've done some searches but haven't really found a definite answer. My car is all stock except cone filter intake and the driftmotion intercooler and hard pipes.
