Basically in English, you can't do a thing to your car. My suggestion is buy something badass from the factory so that it is from the manufacturer. If you wanna do anything to your car, move to SC or Florida. Some states dont even require inspections of any sort. But since Virginia is beautiful and in such demand to reside in (haha) lawmakers have us living in a planned community type setting. I've said this before, if this state had its way as far as motor vehicles, there would be no SUV's, sports car, or anything with over 200hp. Nothing but white Buick Centurys with the 3.1 V6.
