I'm starting to price compare for a new muffler (flowmaster perhaps). What's the inlet and outlet for the VX. Not real sure as to what I'm looking for yet. Maybe the super 40 or maybe something a bit more aggressive. Any part #'s, comments, suggestions? Also.. Has any one bought the Headrest badge off ebay? (item #7971007585) One of his feedbacks said "I wouldn't suggest this seller to my worst enemy." lol Any one care to vouch for this guy? They look nice in the pic but I dont want care to waste my time or the lil money I have.
