Id say replace the res with a glasspack and then get this Cherry Bomb Exhaust :: High Performance Exhaust Systems, Cat-Back Systems, Mufflers and Glasspacks :: Disturbing the Peace Since 1968 best of both worlds as soon as I get a little extra money thats what I plan on doing whole setup for me around $175 installed but I already have the 3in exhaust pipe. Its reversible so u can install it anyway u want like take dual exhaust into single (why you would want to ???)
