My wifes 01 is in need of an exhaust and i was thinking about headers back. Ill need a high flow cat H and a cat back. Im not real familiar with teh 4.6 motors and what exhaust sounds good on them but we're looking for something thats not real loud, maybe a medium on the loud scale (stock is quiet, open headers loud) I have pypes on my 88 and like them alright, never heard them on a mod motor. Brassini, Borla and the like are going to be out of my price range.
