Simple Installation:
All systems use factory mounting locations providing stability and 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 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 5" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.

Polished Tip Option:
Finishing off the exhaust is a high luster, polished 304 stainless steel slash-cut exhaust tip. This tip features a drain port on the bottom to keep rust and corrosion away.

Massive 7" Black Tip Option:
Finishing off the exhaust is a powder-coated black 304 stainless steel exhaust tip. This tip features 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.

Note:
Does not fit 2016 3500HD w/ NOX Sensor

Legality:
This part does not require a CARB EO#

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