AFE 49-14017NM Large Bore HD Down-Pipe Back No Muffler Exhaust System
Mfg. Number: 49-14017NM
XDP Part Number: AFE49-14017NM
|The LARGE Bore HD exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4" stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGT’s. The system is available in a 4" down-pipe back without muffler. LARGE Bore HD exhaust systems are the perfect combination of performance, fit and value.
Installation is a Snap:
All systems use factory mounting locations providing stability and a hassle-free installation.
High quality OE-style flange and band clamps are used for a complete 360 degree sealing surface.
A muffler-delete pipe is used for a true race-inspired sound and maximum flow.
OE-style hangers with bayonet tip are used to maintain a stable pipe location during high vibration and high heat conditions.
Flow and Performance:
LARGE Bore HD exhaust systems are 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.

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.
