Every part of this exhaust is top quality and will easily outlast the truck. Install took about two hours and was pretty easy overall with no permanent alterations to the truck necessary. It is just slightly louder than the stock exhaust, if you want loud this is not the one for you. In my opinion it is a perfect combination of a mild rumble that is not obnoxious. Just wish it wasn't so expensive.

Noticed immediate acceleration increase which is what I was after. I have not checked the mpg yet. The sound was exacty what I was after not too loud but has a nice tone. Had it installed professionally and they said it was a little tricky to put on but not too bad. All in all I love it!
