Rick,

Magnaflow sounds like a great deal at $458, a lot cheaper than most of these systems.

I'm running the Corsa dual outlet exhaust system with stock air cleaner. Similiar observations with the Corsa also. On the outside kind of a nice inline BMW 6 banger sound. Inside quiet at cruise on flat ground, more sound when accelerating and a bit of droning under load climbing long hills. I only feel some power increase when accelerating hard in the 4-6K rev range.

Looking forward to seeing your pics later.
