I've got my pacesetter Long tubes on my 96 and now I need to decide what kind of exhaust to go with. I tossed the cats and have a offroad y pipe but my question is. Should I look into true duals with a x or h pipe? Or should I just keep the y pipe and go with a good cat back exhaust? I was looking into the flowmaster cat back that comes with a 80 series. I'd like for the car to sound pretty mean. Do true duals add much power or sound??
