aFe Twisted Steel Headers 07-11 Jeep Wrangler (JK) V6-3.8L

aFe Power's New Twisted Steel Headers deliver +6 HP and +6 lbs. x ft. torque over the factory exhaust manifolds. The headers are constructed of 1-1/2" 14-gauge 409 stainless steel tubing with 3/8" thick flanges to ensure a leak free seal. To eliminate dead space that can cause turbulence and hinder flow that formed collectors are prone to produce, true mitered collectors are used for true pulse control technology improving flow and performance. The smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. 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 increases exhaust velocity. The result is increased horsepower, torque and improved throttle response. Heavy Duty Flanges: 3/8" thick flanges prevent warpage to ensure a leak-free seal over the life of the vehicle. Note 1: aFe recommends purchasing spark plug wire boot protectors (P/N: 48-90001) and gaskets (P/N: 48-90004) for additional protection for a hassle-free installation. Spark plug boot protectors provide up to 1600F protection for your spark plug wires. Gaskets ensure a leak free seal for a hassle-free installation. Note 2: This system is not currently CARB exempt and is not available for sale in California or for use on any vehicle registered with the California Department of Motor Vehicle.This Part Fits: Year Make Model Submodel 2011 Jeep Wrangler 70th Anniversary 2007-2011 Jeep Wrangler Rubicon 2007-2011 Jeep Wrangler Sahara 2010-2011 Jeep Wrangler Sport 2011 Jeep Wrangler Unlimited 70th Anniversary 2007-2011 Jeep Wrangler Unlimited Rubicon 2007-2011 Jeep Wrangler Unlimited Sahara 2010-2011 Jeep Wrangler Unlimited Sport 2007-2010 Jeep Wrangler Unlimited X 2007-2010 Jeep Wrangler X
