The exhaust looks great but sounds terrible. Just had to order a resonator to see if helps with how loud and cheap sounding the muffler is. Also had to cut off the downpipe hanger because it would not line up.

Well made

Installation was a breeze. The only set back was the hanger on the down pipe. It's orientation was slightly off. My fix was not to use it, instead I used one of the supplied hanger clamps in its place. I also used all stepped SS band clamps at all the joints and would recommend that to everyone. All in all very happy. This is my 3rd truck with MBRP turbo back exhaust.

Excellent system! Easy install and looks great. Sounds good too. Wife says the new exhaust makes the cummins sound like it has a little attitude but is not obnoxious. What better endorsement can you ask for if the wife likes it!
