So this is a sheet metal ringing/clacking, not an exhaust drone? I think of "drone" being an unpleasant resonant pulse of the exhaust gas sound waves caused by constructive waves superposition at certain frequencies (rpm). This is sometimes called "beat frequency" and is the bane of twin-engined airplane pilots.
