I know they're not all out yet, but what would be my realistic HP gain on a new performance cat-back exhaust system without an electronic tune (Hondata, etc....)
Without a tune I would expect the same or even a loss of HP as the ECU would try to compensate for the loss of back pressure while trying to maintain all other parameter settings.
A couple maybe, looks and better sound at this point. Vit just commented on this on another forum and said this engine does not make anymore power with a larger exhaust....for those who only care about power.
