A similar drone is when in 7th at 45 mph and applying the gas - I think you get the picture. Just shift more aggressively and don't try to save gas by lugging the motor.

I think the key here is to know what you are. I am a maniac - like power, speed, noise, gas/oil fumes, and burning tires. A full throttle as often as possible type of guy and my wife is very similar. If you like quiet journeys with gentle breezes and french wine - do not get this exhaust. I drink single malt scotch neat.
We are both the same. Love an aggressive exhaust. Throttle tip in drone is not a big deal. Can't handle a steady drone at highway speed. I would expect most any aftermarket exhaust to have a low rpm tip in drone. As long as it goes away it's all good.
