California car enthusiasts love to modify their cars, from exhaust systems to window tinting to neon underglow lighting.

Illegal: Loud Exhaust Systems
If you want people to hear your car before they see it, make sure it’s not illegal to have a loud exhaust.

California changed its exhaust law in 2019 so that having a loud muffler is no longer just a fix-it ticket but rather a ticketed fine. In short, vehicles must have a muffler that prevents “excessive noise from the exhaust system.”
