Give your 2017-2019 GM 6.6L Duramax a custom look while enhancing exhaust flow with the AFE 49-04085 ATLAS 5″ Filter-Back Exhaust System. Constructed from 5″ mandrel-bent aluminized tubing, this kit uses high-quality band clamps and OE style bayonet hangers for secure fitment. This exhaust system utilizes factory mounting locations to provide a quick, hassle-free installation. Each kit includes your choice of a polished, or black powder coated, intercooled tip with a laser cut stainless steel AFE power badge.

Simple Installation:

All systems use factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal:

High quality band clamps are included for a complete 360 degree sealing surface.

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 Mach FORCE-Xp exhaust system is constructed of 5" mandrel-bent aluminized tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.

6″Diameter Intercooled Tip:

Finishing off the exhaust is your choice of a black powder coated, or polished 6″ diameter, stainless steel slash cut tip with intercooling vents designed to reduce exhaust gas temperatures at the tailpipe. A unique stainless steel laser-cut aFe Power logo plate is riveted on for an aggressive style.
