Aesthetics and function. That’s what you get with aFe’s Large Bore-HD 4” 409 Stainless Steel DPF-Back Exhaust system for your GM Duramax.

Single To Dual Exhaust Conversion:

This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust.

Simple Installation:

All systems use factory mounting locations providing stability and hassle-free installation.

OE Fit:

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 Large Bore-HD 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.

OPTIONS:
  • 6” Massive Polished Tips: Dual high luster, polished 304 stainless steel slash-cut tips. The tips feature a drain port on the bottom to keep rust and corrosion away.
