There is no need for the extra flow on NA cars. I am putting the AAM 3" exhaust on my car (parts go on next weekend), but that is in preparation for turbos. There is only a half inch difference so if you are going to stay NA then a 2.5 should be fine. With the extra flow I could lose some torque from the loss of back pressure but it should be fine. IMHO.
