Yes. If you get lets say a 2.5 or 3in dp catted dp, it will bolt up right up to the catback and headers. If it is catless it will bolt-up as well. Just make sure if you go the catless route, that its legal in your state (emissions). Did you have any issues bolting the catback to the cat on your car? If not, then you should'nt have any problems. If you get a shorty, it has to be welded to your cat. It has a flange to bolt up to the headers.
