Remember that Borla I installed? Yeah well, 1.5 years of drone was enough for me (and my wife). I got the Borla in the first place just to let the car breathe better; I'm not one for making my luxury sports sedan heard from miles away. That said, I do enjoy a good exhaust note. With the Borla, at crusing RPM's, the bass in the cabin was too much. An opportunity to sell it came up, so I went for it and got the AWE Twin2 instead. I'm happy as can be. The drone is GONE, and it actually has a much crisper sound than the Borla did; very nice and hearty while not overwhelming. Data says it's still quite a bit louder than stock (and now with downpipes it most definitely is).   This one, I installed myself in the garage. AWE even supplies nice instructions. Really not much more to say than that...a welcome addition to the S.
