Stock-ish 5.7 Build...2.5" or 3" Exhaust?
Im for the 2 1/2" also, but maybe use the 3" for the end pipes. They tell me that they will add a little but looks is more what it will do. Just a clean, non restrictive muffled exhaust should do just fine. I'm looking that truck 395 hp 5.7 too. For me, in a street Valiant, I think that 485 hp is a bit much for the street. Maybe I'll regret it, but that's my thoughts. 400 hp in a 2900 lbs Valiant, that should suffice.
