    I was wondering if the exhaust noise level restrictions (i think its 70 decibels) are when the car is idling or revving, and if you can add an aftermarket exhaust that increases the sound of the car

    Here's the statute:

    Paragraph A is subjective and I found no case law on it.

    You can google decibel level charts and get plenty of them. 70 to 75 decibels is pretty tame. 80 and up gets annoying.

    What level attracts the attention of a cop is anybody's guess. But if you push the envelope too far you could find yourself cited for it.

    For the first question, the answer is "yes".

    Thanks for the answers, i wasnt sure if id get arrested going one decibel over lol. Im planning on getting an exhaust that gets up to 75-80 midway up the rpm range when a few feet away from the car so i think it’ll be fine as long as i dont rev it like crazy

    I suggest you also buy a decibel meter and not just rely on manufacturer's of seller's specs. Carry it with you in your car in case you are stopped.

    Come to think of it, I should probably get one. My Viper is pretty loud. Though I haven't been pulled over for it.

    One might interpret the statute that Jack quoted as prohibiting a modified exhaust system that is louder than stock.

    Personally, I would consider such an exhaust system to be producing "unusual noise", in violation of the statute.
