Most of the aftermarket cat back exhausts are making 13-18 additional and the only difference from what I am planning is the mufflers they use.
The stock muffler from what I have seen isn't a problem. The most restrictive part of the exhaust setup is the Y-pipe which will be replaced with a true dual exhaust setup.
