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.

Specially Formed End Connection:
A specially formed end connection was designed which helps the exhaust system attach directly to the DPF.

Flow and Performance:
This Large Bore-HD exhaust system is constructed of 5" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.

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

Note: Fits 160.5" & 160" Wheel-Base

All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
