speeding ticket on 81

[Feersty]

(Nearly) Every car I ever saw pulled over was out of state and many of those w/ tinted windows.

Can you really get a ticket for tinted windows with out of state plates?
In Texas its legal for my car to have 20% Tint in the front and no limit on the back. I have 20% in the front and 5% in the back on my Acura. I've never been hassled for it by a VA cop. I've been pulled over once for a bad tail light, and been followed across town for no reason. Neither times did they mention my Tint and its pretty damn dark.
I was planning to put an exhaust on my car over the summer, in hopes that im exempt from VA law, since my license and registration are in Texas.
Anyone know a true answer on law for out of state drivers?

Don't you have to get a VA license and plates after being here for a certain amount of time? I think military are the only ones exempt.
