would it be worthwhile to weld a flo pro 2501 in place of my stock muffler on a 5.3L V8 truck? or can anyone come up with something that would look almost completely stock (not rust) where i can swing 3"?

 

just throw a stainless catback on

 

I plan on doing the same, but running a dual in/out 2.5". I am going to cut at the y where the duals come in and run two 2.5" pipes in to the muffler and exit out somewhere. Just a thought, its true duals with an internal x over. Saves the extra cost of the x over in one muffler.
