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.
I have Eisenmann Sport. Granted it could be psychological; however the car does seem to breathe much better; especially at high RPM's..more sensitive to throttle input. Keep in mind, these are only mufflers and not a full exhaust systems, so change in HP is negligible
