Possible small exhaust system crack? It closes up as the system gets warm? Will only get louder as the crack deteriorates, if that's the problem.
If you like that deep throaty rumble sound versus the putt-putt Model T sound. A Solo performance side exit exhaust system may be what you should look at if you have to replace your exhaust system.
Good luck and keep us updated.
