Any drone with the Flowmaster muffler? My experience with Flowmasters on Mustangs was almost always a lot of drone.
Did you leave the “interior sound” on or turn it off?
I have no drone at any speed. I left the factory resonator to keep the noise levels down inside the cab. I have not turned off the interior sounds.
