Keep in mind, people love to throw stupid large heavy wheels on their cars and it's no different. If you can get lighter wheels, tires, driveshaft, flywheel, and crank pulley you're looking at seriously increasing WHP without touching the exhaust.

I thought it was header and overpipe? I was under the impression that the rest of the exhaust flows pretty well. The stop up is in the front.
