welcome love the username :D, and congrats, pics are always nice
i wouldnt call the 2.2L any sort of performance car, very limited aftermarket and still w/o tuning so your "uber" mods arnt going to be performing the greatest. GMPP parts are nice, especialy if/when the cops want to give you a hard time, all you have to do is point to the chevy logo on the tip and say, "what? no, thats factory." and smile

but you are going to loose some low end (torque) with prety much any sort of aftermarket exaust out there, and IMO, the 2.2L's low end is it's best trait.
good luck and happy modding
