2011 Mustang GT Hushpower - Resonator Delete

Here's my 2011 Mustang GT with Flowmaster Hushpower Axlebacks and a resonator delete by a local muffler shop. Sorry for all of the background noise...it was a very windy day. I'll try to get a better video on an HD camcorder. There's no difference in sound volume at idle and cruising. You really hear the difference when revving and accelerating. It sounds a lot more throaty during acceleration.

There have been posts that removing the resonators makes the exhaust obnoxious, but if you notice, they have already removed their catalytic converters. Just removing the resonators increases the sound volume when revving and accelerating, but not nearly as much as removing the catalytic converters, and there is no issue with emissions/warranty. I have not noticed any increase in drone either.

The only time I hear this drone is going up a tall hill at 1800-2000 rpms...which is very rarely, then I shift into 5th until I get up the hill. The only reason it drones during this is because the engine is in to high of a gear (6th) for the speed and elevation of the hill...that's why the automatics have such a problem with drone, because of the fuel saving technology which puts them in a higher gear to save fuel (I think I'm saying this right). I'll work on getting a video of inside the car at cruising speeds and acceleration.
