aFe Power Exhaust Systems

aFe Power Exhaust Systems

aFe Power Exhaust Systems are engineered to perform, creating more horsepower (HP), torque and air flow, which will result in better fuel efficiency and performance for your diesel truck. Each exhaust system is made from mandrel bent stainless steel tubing or aluminized steel (as with the Atlas & LARGE Bore lines) for unobstructed maximum flow, increased horsepower, increased torque and lower EGT’s. aFe Exhausts are a snap to install, by utilizing factory mounting locations and attached with OE style bayonet hangers which 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. With aFe Exhaust Systems, you're guaranteed a quality Leak-Free, Perfect-Fit exhaust with an aggressive sound, providing increased flow and performance for your Dodge Cummins, Ford Powerstroke and GM Duramax diesel trucks.
