aFe 49-44040 5″ 409 Stainless Steel DPF-Back Exhaust System

Flow and Performance:
The aFe 49-44040 5″ 409 Stainless Steel DPF-Back Exhaust System is constructed from 5″ mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower and torque and lowering EGTs.

Simple Installation:
All systems use factory mounting locations, providing stability and a hassle-free installation.

Leak-Free Seal:
High-quality OE-style flange and band clamps are used for a complete 360-degree sealing surface.

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.
