AFE 49-44043-X Mach Force XP 4" Dual DPF-Back Exhaust System

The AFE 49-44043 Mach Force XP 4" Dual Exhaust System is a sure way to increase flow and add some styling to your 2011-2016 Duramax LML. This system is built from 4" Stainless steel tubing and re-installs using factory mounting locations. Designed 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. 

This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust.

This exhaust system fits perfectly without relocating the spare tire.

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. 

This Mach FORCE XP exhaust system is constructed from 4"" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.

Note: This exhaust system fits 2016 2500HD models without the NOX Sensor. Not for use on Cab & Chassis models.
