aFe 49-44043-P 4″ 409 Stainless Steel DPF-Back Exhaust System

Built with 4″ mandrel-bent 409 stainless steel tubing for maximum flow, the smooth transition bends of the aFe 49-44043-P 4″ 409 Stainless Steel DPF-Back Exhaust System allow for low turbulence, increasing horsepower and torque and lowering EGTs. This unit uses all factory mounting locations and comes with a bolt-on bracket that supports the driver-side tailpipe. This provides for a quick, hassle-free installation with no modification necessary.

This system uses high-quality band clamps and OE-style bayonet hangers. Also included is a massive 6″ polished 304 stainless-steel tip with a laser-cut stainless-steel aFe POWER badge.

Note: This system does not fit the 2016 3500HD with NOx Sensor.
