I don't know about other
I don't know about other states, but in NJ the state gov stopped requiring inspections and every year the intrusive and incessant modified exhausts has steadily gotten worse.
Young kids are basically trolling society with their noisemakers in the most cowardly, entitled way imaginable, treating public roads like their own personal Fast and Furious fantasy playground.
Every now and then, a loud car doesn't bother most reasonable people. But the current fascination with insanely loud extreme exhausts is a source of constant torment for people because it is so intrusive and incessant. NJ sounds like a formula one racetrack now. As if we needed our roads to be more rage filled and obnoxious.
Do what you want with your cars kids, but when it's intrusive into people's homes, the one place where they can chill, then you're being an entitled asshole.
