It's a bit louder than I wanted but I do love it!

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.

Exhaust produces a very nice sound. Unfortunately it is quite a bit louder inside my cab than I expected. Looking at ways to dampen the sound currently, when pulling anything you cannot hear anything and the Mrs's isn't to pleased with that. Much louder than other moderate exhausts I have had in the past.
