Just got back from the shop...I can't believe how big the gains were, just from putting the Corsa on there. 26.4 ft-lbs of torque increase, 16.2 hp gain! I'm putting in the Stage 1 kit from lightning force performance (intake, thermostat, and predator) as soon as it gets here. I'll post dyno results soon as I get all that on the car.

I am definitely a noise guy, but the Corsa is just right for me for now. Eventually I'll need some LT's to get some noise in there...Corsa changes the pitch of the exhaust note as well, and it is a welcome change...
