I am ready to buy my aeroturbine exhaust right now. i have a very big decision problem with the AT3030 or the AT3030xl. i am going to keep my stock resonator but i want some good sound with a real deep bass tone. I want to hear it on acceleration but not on cruise(a little sound on cruise is ok). I called and was told performance was the same but the AT3030xl will make the deepest sound, but im really scared that i wont get enough sound. please help.
