aFe 49-04043-B 4″ Aluminized Steel DPF-Back Exhaust System with Black Tips

Flow and Performance:
The aFe 49-04043-B 4″ Aluminized Steel DPF-Back Exhaust System with Black Tips 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.

Massive 6″ Black Tips:
Dual powder-coated high-temp black 304 stainless-steel tips finish off the exhaust unit. The tips feature a drain port on the bottom to keep rust and corrosion away. A unique stainless-steel laser-cut aFe POWER logo plate is riveted on for an aggressive style.

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