The install was simple and easy, had it on in a few hours. The sound is great! It's not obnoxious but still has a low growl. It's a little droney at low speeds right before the truck shifts but its tolerable. The AFM doesn't seem to affect the sound qualiity too much, it just gets quieter. Overall, I'm extremely happy with my purchase and would reccomend this exhaust to anyone running the 5.3L.
