well, while im not supercharged yet, i plan to be. like i said, i just bought the car. i have a mac cai, performance crankshaft and camshafts, rolling rockers, diable sport chip, underdrive crank pulley set, steeda lowering springs, other body work, and i might of forgot a thing of two. anyways, this car has become quite a project for me. I want the optimum exhaust setup because of what the engine will potentially be when im done with it. still not sure of what combination of products will fit, though.
