Be carefull if you have VA tags and goto that meet. Last time they had something like that in VA, the police were waiting outside and ticketing everyone for "crimes" ranging from no front plate to ugly date. They gave out tickets for :
Aftermarket exhast- according to them, it is illegal to have an exhaust other than the one your car originally came with. They need to go Midas and write tons of tickets then!
No Front plate- Obvious
HIDS- Guess what? same as exhaust (the fake me out blue bulbs they wont have a problem with.
Nitrous - Might get a waiver if you are dentist, but other than that, you'll get a ticket if you are lucky, towed if not.
