Application: 07.5-10 GM 6.6L Duramax LMM
The Mach FORCE XP exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4"" stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGT’s. The system is available in a 4"" down-pipe back with muffler and is finished off with a powder-coated black or polished tip. Mach FORCE XP exhaust systems are the perfect combination of performance, fit and value.
Installation is a Snap:
All systems use factory mounting locations providing stability and a hassle-free installation.
High quality OE-style flange and band clamps are used for a complete 360 degree sealing surface.
A free-flowing 24"" x 8"" long muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig.
OE-style hangers with bayonet tip are used to maintain a stable pipe location during high vibration and high heat conditions.
Flow and Performance:
Mach FORCE XP exhaust systems are 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.
Finishing off the exhaust is a polished or powder-coated black 304 stainless steel exhaust tip. This tip features a drain port on the bottom to keep rust and corrosion away. A unique stainless steel laser-cut aFe Power logo plate is riveted on for an aggressive style.

What is the DPF?
DPF is an acronym for Diesel Particulate Filter. A DPF works in
conjunction with the oxidation catalyst and EGR valve to remove a
majority of the NOx, particulate matter (think black, cough-inducing
soot) and unburned hydrocarbons from burned diesel fuel. Soot is a
natural byproduct from the combustion of diesel fuel. Inside the DPF is a
porous honeycomb structure that catches the soot as it passes through.
After the soot builds up over time, the onboard computer controls fuel
injection to allow unburned fuel to enter the filter at measured
intervals where it flares off and generates increased temperatures that
incinerate the accumulated soot. The result: Soot is chopped by over 90-percent.
What do I need?
Step 1: EXHAUST - Select a Complete DPF Delete Exhaust System or DPF Delete Race Pipe
Step 2: ELECTRONICS - You must select an electronic performance unit for the exhaust to work properly with your vehicle.
You MUST use DPF delete capable electronics when removing the DPF off
of the vehicle. In addition, running DPF delete tunes without removing
the DPF will result in engine codes and filter blockage.
