The AFE 49-44064 Large Bore HD 3-1/2" DPF-Back Exhaust System for your 2016-2017 GM Colorado/Canyon 2.8L Duramax is designed to increase flow and looks. Constructed from 3-1/2" mandrel-bent stainless 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 exhaust tip with a laser-cut stainless steel AFE Power badge.
This system uses factory mounting locations providing stability and hassle-free installation.
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.
