There is no drone at all at highway speeds or under load. Ok maybe a slight humming sound at 2k rpm which I didn't like at first but putting it in sports mode solved it (crusing at ~2.3k rpm seemed to solve the problem). But now I either got used to it or the exhaust has "broken in", I drive on the highway in comfort mode without being bothered by the exhaust.
