AFE DPF Race Powerstroke Exhaust (without bungs)
The aFe Mach Force XP down pipe back race exhaust system
eliminates the use of the restrictive diesel particulate filter (DPF)
for maximum performance out of your Super Duty
with the Power Stroke 6.4L. This free flowing exhaust system is
constructed out of durable 4" 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 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.
F.A.Q about Bungs - Bungs are the ports in which you would reinstall your
factory sensors. A system with the bungs is suggested if you are running a
performance chip/tuner that has gauges so you will be able to read temps from
your factory sensors. This will prevent you from having to install a pyrometer
(egt sensor) into your exhaust manifold.

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.
