If its a cat back system its already bent to match right up to your stock cat location depending of course if u have a single cat or a duel cat setup, as far as headers ive been checking out edlebrocks ti-tech coated ones 400 bucks and they fit just like the factory exhaust mani's and are also 50 state legal
