I have a 2002 Z06 Corvette and it is bone stock....That's a problem. I want to start with some stuff very small...

Maybe an intake system, exhaust system, and some different headlights. I saw a guy with headlights that don't flip up with 6000K HIDS..it looked SICK. I think he said they were C5-R headlights??? If anybody has any ideas or whatever...Just post em' up or PM me! Your help would be greatly appreciated. Thanks...
