Performance Exhaust = Ass Like Accel

[Hanaldo]

Technically you want exhaust velocity, not backpressure... I would be surprised if your 2.5" exhaust was too big, it should be ok. Not trolling, but are you sure it's not just a case of having a slow NA? lol. Or as Ash said, you've altered the cars load points and affected the tune, though the stock ecu should be able to relearn for such a small mod.
