huh these are the two exhausts that i am in between and do not know which one to do. I used to have a stillen exhaust on my g35 coupe and i absolutely loved the deep sound. I am leaning towards the cp-e b/c i feel like the AA exhaust is too loud at idle and would drive me banana's.

Is the cp-e loud at idle or only when you open it up?
