The aFe Mach
Force XP Race pipe upgrade kit is constructed of mandrel bent 409
stainless steel with OE style hangers and clamps. This 4" race pipe
provides maximum flow for increased horsepower, torque and throttle
response. The increased air flow also lowers EGT's. All hardware and
components are included for a no-trouble installation. DPF-Delete Only.
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.
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.

I just put it on so only have been driving with it for a couple days. It is a great product. If you are deleting the dpf to get better sound you will also have to get rid of the cat. I did notice difference when on the gas but not at idle. So I will be cutting the cat in the near future.
