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.

Polished Tip:
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 (OPTIONAL):
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.

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