The AFE 49-44075 Large Bore HD 3" Turbo-Back Exhaust System adds styling, flow, and race performance to your 2016-2017 GM Colorado/Canyon 2.8L Duramax. Constructed from 3" mandrel bent stainless steel tubing, this stainless steel turbo-back exhaust system is specially engineered to utilize all factory mounting locations for a quick, hassle-free installation. 

Simple Installation:
This system uses factory mounting locations providing stability and hassle-free installation.

OE Fit:
OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time.

Flow and Performance:
This Large Bore-HD exhaust system is constructed of 3" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.

4-1/2" Diameter Exhaust Tip:
Finishing off the exhaust is your choice of a 4-1/2" diameter, black or polished stainless steel slash cut tip with a unique stainless steel laser-cut aFe Power logo plate riveted on for an aggressive style.

So glad I went with afe. Easy to install. I went with no muffler and it sounds bad azz. The turbo whistle is great and the flow is amazing.

Location: Colorado
This exhaust was an easy install, quick to fit up under the truck and looks great. After installing it and double checking for loose hardware I was ready to drive. I purchased the turboback with muffler and black tip. The sound was aggressive but not overly loud. Under partial throttle it maintained just enough sound to remind me I had an exhaust but enough that I could also forget it was there when cruising. Zero drone on the highway and a definite head turner on the street. 100% would recommend
