I know a number of classic wooden boats with no sound deadening devices. The are loud but with the sweet mellow 'flat head sound'. Do they ever get stop? Old man Foley with his 30's something raceboat goes out almost every morning with his 12 cylinder Packard singing. You can see the 12 'mega phones' sticking out the engine hatch. he's been doing this for decades. Never been pulled over.
Sweet sound to my ears.....................
