Varies municipality to municipality kids. In some states, such as NC, its flat out " Reckless Driving", a misdemeanor that can land you in jail and your car impounded. The police here usually wont get that bad unless you get an attitude.
up here its called "excessive noise of exhaust or tire contact" thats a $75 traffic ticket with no points.....
but like everyone said the cops have all the power and pretty much make all the rules, im sure it wouldnt take much to get a guy with reckless driving or dangerous driving best bet is dont get caught

I dont know where to get them or who makes them. I know they were a trend here in San Antonio a few years ago. I remember KSAT12 news did some coverage on them. Haven't seen any cars with 'em for a long time though.
