The aFe Mach Force XP DPF-Delete race turbo back exhaust system eliminates the use of the restrictive diesel particulate filter (DPF) for maximum off-road performance. This free flowing exhaust system is constructed out of durable 5" mandrel bent 409 stainless steel and uses bayonet style hangers and band clamps for a clean installation. This system comes complete with all tubing, bayonet hangers, band clamps, thermocouple and pressure tap bungs.
All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.

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.
Warning: 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.
