Awsome exhaust system

Reviewed By Robert C (Chino Valley, AZ) Reviewed for a 2014 GMC Sierra —8/12/2017 6:26 PM

I saw improved performance immediately, in addition, I got a cool throaty sound as well. If you're looking for either of these two features, I would strongly recommend this exhaust.

Looks awesome, easy as hell to install. The sound is nothing special. It's defiantly much louder vs stock.
