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