The aFe Mach Force XP DPF-Delete race front-pipe back exhaust system
eliminates the use of the restrictive diesel particulate filter (DPF)
for maximum performance. This free flowing
exhaust system outflows the factory exhaust by 300cfm 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, muffler, bayonet hangers, band clamps and is
finished off with a high luster polished 304 stainless steel, rolled,
slash cut tip. This system requires the use
of a controller with a DPF-delete function.
Note: This system weighs 85lbs less than the factory exhaust for increased performance.
This is a "Race Only" product section used solely for competition. Its use is limited to closed-course racing that is formally sanctioned by a recognized racing organization. Any other use, including recreational off-road use, could be in violation of local, state and federal laws.
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.
