Exhaust upgrade, RPM acceleration increase?

The only sport exhaust I've ever had installed was on a motorcycle and car. On the motorbike, a '94 FZR 600. It was apparent that the sport 4-into-1 exhaust system made a difference on performance/sound. On my '04 Saab 93 Aero which is a turbo 4cyl. I had a Borla muffler installed and it was noticable that the engine would spool up RPM's a bit faster.

So with the M3 V8, anyone that has installed a Remus, Corsa, Eisenman, etc. Exhaust system CAT-back notice a difference in performance? The sound is obvious but do you think the engine increases RPM's any faster? I know Remus states a 8hp gain at the wheel but just wondering if the acceleration is improved. thanks fella's.
