aFe Twisted Steel Exhaust Header for 2011-2014 Ford F-150 (48-43001)

Product Description

Add more power to your 2011-2014 F150 Coyote with the 5.0L by installing our Twisted Steel headers. These headers feature 1-5/8" mandrel-bent tuned length primary tubes that will outflow the stock cast manifolds by 46%. These headers are built using 409 stainless steel and feature thick 3/8" flanges for a leak-free seal. We designed the headers to incorporate a merge collector (header collector). A merge collector combines high flow and velocity to increase and broaden the engines torque curve, while reducing turbulence that is found in traditional form collectors. When combined with our off-road or catted y-pipes, performance gains increased as much as 10 HP and 20 lbs. x ft of torque over the stock manifolds and factory Y-pipe. Factory Mounting Locations: These headers retain your stock catalytic converters and are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation. Mitered Collectors: Mitered collectors decrease turbulence and increase exhaust velocity. The result is increased horsepower, torque and improved throttle response. Heavy-Duty Flanges: Thick flanges prevent warpage to ensure a leak-free seal over the life of the vehicle. Emissions Disclaimer: This product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles. aFe POWER headers are engineered and manufactured in our Corona, California manufacturing facility.
