Atlas 4" Aluminized Cat-Back Exhaust System | Ford F-150 11-13 EcoBoost V6-3.5L | No Muffler, No Tip | AFE 49-03041NM

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
