The AFE 49-04044 ATLAS 4" Dual Downpipe-Back Exhaust System is constructed from 4" mandrel-bent aluminized steel. This exhaust system will provide a mild, throaty tone with a 12" long muffler and installs easily with high-quality band clamps and OE-style bayonet hangers. Designed for ease of install, this exhaust system will reinstall using the factory mounting locations and comes complete with a bolt-on bracket that supports the driver side tailpipe. The finishing touch is your choice of a polished or powdercoated exhaust tip. ATLAS exhaust systems are the perfect combination of performance, fit and value.
Single To Dual Exhaust Conversion:
This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust.
Fits With Spare Tire:
This exhaust system fits perfectly without relocating the spare tire.
OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time.
Flow and Performance:
This ATLAS exhaust system is 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.
This exhaust system uses a mitered merge collector to convert the standard single exhaust to an aggressive dual exhaust.

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.
