Now if you have emissions testing, an axle back will free up some sound.

Muffler deletes are trash by the way, don't do that. If you have an n26 with the secondary catalytic converter, and you are again in a nonemissions state, I would delete that.
omg i forgot about that. i live in missouri and i have no idea if they testing for my exhaust! im scared now to put an exhaust on. i dont plan on tuning so do you suggest doing a downpipe or rear axle back? I plan on just doing only one and keeping the rest stock.
