Honestly, in a car with stock DPs its not terrible, about the same as a muffler delete. When I had it with cat less DPs the drone was so bad between 2300 and 2700 you almost had to cover your ears. You could only drive the car balls to the wall or shift under 2300 rpm to enjoy it, otherwise it was a tedious task to drive the car without wanting a pair of ear plugs.
