Running true duals with no H or X pipe will cost you performance. First off, it will add weight to the car that isn't needed. And H and X pipes are proven to add power by helping with the exhaust scavenging in each cylinder.

A standard 3" catback is more than enough flow for most applications, and if you plan on going all out, Mufflex sells a 4" system that fits in the stock location.
