The AFE ATLAS system is constructed from 5″ mandrel-bent aluminized steel tubing and uses high quality band clamps and OE-style bayonet hangers. This unit uses all factory mounting locations to provide a quick, hassle-free installation. ATLAS exhaust systems are the perfect combination of performance, fit and value. All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.

Simple 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.
