One of the best upgrades ever!
It was installed professionally! I would not recommend the installation. The truck drives differently, better. The MPG is way better now. I am happy with this upgrade.

Easy install
This product was easy to install and only required a little bit if pressure with a mallet for a good tight fit. I’m putting these in all my trucks.

2020 RST - ClintDeVine
Nice product
Excellent product, adds a little more noise to the 3.0 diesel and allows for better airflow with no restrictions. I have no clue if it adds power but I can tell the truck sounds better.

PPE Dual Exhaust System
This exhaust system sounds great! Gets loud enough when you get on it and quiets down when cruising also has a nice deep tone

Awesome sound!
Removed the turbo resonator and installed this item as well as the S&B cold air intake. What a difference! This product definitely gives a beefier tone to the Duramax motor!! When installing, make sure to line it up properly.

Perfect Fit
Support bracket fit just as expected. New up-pipe didn’t come with necessary support bracket and this one fit.
