yeah, you dont need a 3inch downpipe...Go 2.25 or 2.5, its better anyway that way if it goes from that to a 3 inch all the way back. Just get a custom 2.25 downpipe made from a local exhaust shop that doesnt care if you have a cat or not (cuz you are going to bypass the cat when you do a custom downpipe).
