I have a 95 F150, 4.9 Six. I want to put a performance muffler on my truck, but not sure which one to go with, Summit Racing makes their own, has anyone tried theirs? Also, if I keep it single out, (one tailpipe) will it still have a good sound to it? And the exhaust exits to the rear of the right rear tire on the right side of the truck as I'm sure yall know, does it hurt performance to have it exit this way? Should be straight back?
