From what I've read, you need the catpipe from an 05 or earlier for the headers to fit, and the catback should fit, stock or aftermarket. Although, with the stock catback, you really can't tell much of a sound difference. Personally, I would (and did) get a trackpipe with the headers, but if you want to stay legal, I still have my stock catpipe somewhere. PM me if you want it for cheap.
