The AFE 49-04064 ATLAS 3-1/2" DPF-Back Exhaust System for your 2016-2020 GM Colorado/Canyon 2.8L Duramax is designed to increase flow and looks giving your GM Colorado or Canyon a custom look. Constructed from 3-1/2" mandrel-bent aluminized steel tubing, this exhaust system uses high quality band clamps and OE style bayonet hangers for a secure fit. Included is your choice of a massive 5" black or polished stainless steel intercooled tip with a laser-cut stainless steel AFE Power badge. 


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 ATLAS exhaust system is constructed of 3-1/2" mandrel-bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.


All aFe exhaust systems are engineered and manufactured in their Corona, California manufacturing facility."
