aFe POWER ATLAS Cat-Back Exhaust w/o Tip (2011-2014 F-150 3.5L EcoBoost)

This Atlas Cat-Back exhaust system is constructed of 4" mandrel-bent aluminized steel tubing, OE style bayonet hangers, band clamps and all hardware necessary for a hassle-free installation. The smooth curves and increased diameter of this exhaust system helps remove restriction and keeps exhaust gas flowing smoothly for increased horsepower and torque.

Installation is a Snap: This Atlas uses all 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 eliminating leak paths.

Aggressive Sound: A muffler delete-pipe is used for a true race-inspired sound and maximum flow.

Perfect 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: Atlas exhaust systems are constructed of 4" mandrel bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and improving throttle response.

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