Can anyone tell me a good sounding (as best as a v6 can sound) exhaust system for 4.3 v6 with out being being obnoxious by saying "just buy a v8" or "itll sound like crap no matter what" i get it i dont have the v8 , i basically wouldnt mind just a dual exahust out the back with the factory muffler, i just like the dual look, is there a kit that converts single tl dual rear outlet from muffler back
