As long as your car has valid registration in your home state you can drive it wherever you want within the 50 states. If you're visiting here and you get pulled over for load exhaust (just for an example) you just tell the officer that it's legal where your car is registered. It's different than say speeding; your car does not have to meet the local smog requirements of some place you're just visiting, but you do have to follow the rules of the road.
