Do these brakes need to be turned off when entering towns that have restrictions stating such, or is that for semi trucks? I have seen that in towns through Nevada and CA.

I personally do not believe that they make enough noise to worry about such restrictions. Those laws are written to stop trucks with "Jake" brakes that sound like this. Problem is that their law is often not enforceable because the truck may not have a "Jake" brake. "Jake brake" is a nickname for the Jacobs Engine Retarding systems. Jacobs manufacturers several type of systems such as exhaust brakes, bleeder brakes, compression release brakes. Adding to the confusion, Cummins, Cat, Mack and others also make engine retarding systems. Your exhaust braking system should not make enough noise to get you into trouble. But it may be best to avoid using it in residential or business district areas.
