Sound Levels in relation to Speed Limits

I have DARPA inserts in the rubber casing of my exhaust. At the time about 20 years ago, that was the latest technology. It uses the water flowing through the exhaust to quiet the engine noise. The faster I go the more water going through the exhaust, the quieter it gets. When I start my engine, it is wicked loud and gets the attention of nearby MPO. I have a piece of paper stating I pass the 'flyby' test. I carry it all the time. If they pass a law that I have to be tested at idle, I am history.
When I first got the boat, I had switchable captain's call. It would be wicked quiet at the docks and in the bays. Once I am on the Broads I will switch it open. I had to get rid of the switchable not only because it is against the law, but to allow room for the DARPA.
What I am saying is if I had both. I can be quiet all the time. Unfortunately the law says otherwise. The law sometimes defeats its own purpose.
