Sounds like a baffle in muffler has come loose and just is bouncing around in the muffler.

Does the sound change pitch if you rev the engine? If so, I'd suspect a bad water pump, alternator, or pulley. Remove the belt(s) for testing purposes only, and see it stops. If it does, we're on the right track. HTH. -Jim
