The AFE 49-04043 ATLAS 4" Dual Exhaust System is a sure way to increase flow and add some styling to your 2011-2015 Duramax LML. This system is built from 4" Aluminized steel tube and installs using the same factory locations as your stock exhaust. Designed as a bolt-on kit, this system also includes all hardware needed for installation of the second tailpipe as well as high quality band clamps and OE-style bayonet hangers. The final touch is your choice of 2 polished or black powdercoated 6" exhaust tips.

Single To Dual Exhaust Conversion:
This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust.

Fits With Spare Tire:

This exhaust system fits perfectly without relocating the spare tire.

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 4" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.
