aFe 49-04043-P 4″ Aluminized Steel DPF-Back Exhaust System

Flow and Performance:
The aFe 49-04043-P 4″ Aluminized Steel DPF-Back Exhaust System is constructed from 4″ mandrel-bent stainless-steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower and torque and lowering EGTs.

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 Fit:
OE-style bayonet hangers 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.

Polished Tips:
Finishing off the exhaust are dual high-luster polished 304 stainless-steel slash-cut tips. The tips feature a drain port at the bottom to keep rust and corrosion away.

Fitment Note:
This item does not fit 2016 3500HD models equipped with a NOx sensor.
