Had my 06 6.0 put back a few weeks ago when I was in GA. It didn't help my MPG as much as I had hoped it would, but the first time the wife got inside the truck she said it's not as loud as it was. I now love the way my Tow-Haul works, when pulling the 5th wheel. Wish the turbo would spool up faster.
My truck is stock.
Thanks again
Doug
