What the size of our exhaust. Before muffler and after muffler. I want to swap out the muffler on my truck. Also what would i need. Offset or center enter/exits
2.5" ID all the way through. I believe the stock muffler is offset in center out but you will be fine with center in offset out, offset in center out, or probably even offset in off set out.
2.5" center / offset... if you want loudest possible, get a small case muffler (14")... if you want mellow yet very audible when at WOT or under load, go for the bigger cases... say Borla Pro xs "XL".
Go with Black Widow Race Venoms and it's a V8, step up to the 3" and have some fun. My brother and myself run these on all of our trucks and they sound awesome!!!
