From my personal experience in terms of loudness and drone.

1. Stock system

2. AA Headers with stock secondaries and stock exhaust - Slightly louder and hard to tell it has headers from just sound. Tame

3. AA Headers with stock secondaries and MagnaFlow Catback - What I have and I think it's perfect. MagnaFlow also includes its own resonator. Sounds kind of like my old E46 M3.

4. Stock exhaust with Muffler Delete - I had this for awhile, and it's actually louder than the option I have now listed above.
