An 04+ GP will have at least one different hanger along the rear bend before the Y-pipe, iirc. It should still hang and line up the same. Be aware that all the ones I've removed have come off in one big piece from behind the downpipe back. You might get lucky and find something with better than stock tips too, never know.
If you'd like a brand new OEM exhaust (I'm guessing not because of cost), Walker Exhaust makes it. It comes in several parts.
