Balancing your budget, noise and performance goals I would: Keep the Borla (or deal with it last if you decide to change it) Go with SZ 4 bolt expansion DPs for performance/availability Go with 3" expansion DPs and 3-2.5 testpipes with cats (cats make a big difference) So I would probably start there personally and then tune the exhaust (resonators or different catback) to your liking after that,
