I found this information when I was looking for state laws concerning exhaust sound level and plate placement.

You can search by state from the pull down. Sorry I could not figure out how to make it a quick link in the message I will try to fix it later but for now you can cut and paste to get the information.
Some interesting information such as the state of Kentucky does not allow aftermarket exhaust that has a sound level that is above the original. It could change your mind on spending $$$ for an aftermarket only to get a ticket along with the deal and have your local law enforcement include you in their ticket quota every month.
