aFe Power's new Twisted Steel header delivers an astounding 8hp and 8lbs. x ft. torque while out flowing the factory exhaust manifold. The header is constructed of 1.5" 14-gauge 409 SS tubing with a 1/2" thick head flange to ensure a leak free seal. To eliminate dead space that can cause turbulence and hindering flow that formed collectors are prone to produce, a true merged collector and optimized tube lengths are used for true pulse control technology improving flow and performance. 100% hand TIG welded construction ensures optimal strength and durability. The smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability on and off the trails. All components are supplied for a hassle-free installation with no modifications necessary. 50 State Legal. CARB Notice 50 State Legal - CARB E.O.
