There is no advantage to a catback on the '03+ cars. Magnaflow did a prototype for an '03 and it only gained 5hp. You can't feel 5hp. Most of our members with the newer cars are opting for muffler swaps and new tips (4" round is popular) I believe the pipes are 2 1/4", but any decent muffler shop should stock whatever you need regardless of what it actually measures. It's certainly nothing exotic.
