ATLAS 4" Aluminized Cat-Back Exhaust System Ford F-150 11-14 EcoBoost V6-3.5L 304 SS Black Tip | AFE 49-03041-B

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 straight through designed, free-flowing aluminized steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig.
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.
