In MA they don't care what you do except maybe in small towns with 2 cops and 1 cruiser that never get anything to do.
When I was a kid putting a cherry bomb on a car would get you pinched as soon as you left the house, ditto bald tires (they wrote them up as racing slicks) from doing burn outs but no more, today PR cars bouncing up the street from having the coils cut down with a torch, tinted windows, extreme camber, fart can mufflers are all on the menu, driving license and reg, we don't need no stinkin license and if they say they are illegal the cops cant push the issue just let them go. Fact!
The cops stop them and its racist, so no more knocking them off the head and throwing them in the cruiser to be locked up, so they just ignore it.
