I posted this in the 'Drone Poll' thread and I thought I would added it here, hope this gives some insight to the designing/developing approach to drone:

But DRONE is:
A continuous, low frequency, monotonous sound.
It doesn't even need to be loud, in fact it is usually under very light load in lower RPM's. Just read what DINAN engineers struggled with on the E9x M3 exhaust they were developing. They state: "We worked at designs that would maintain the dual exhaust outlets but each iteration resulted in a heavy, low frequency drone with far too much back-pressure to produce any substantial power gains." Yet some M3 owners scoffed at the DINAN exhaust because the outer pipes were faux. For me and many others who bought the DINAN exhaust, the real functional gains and the lack of drone was more important.
