### Performance Overview

aFe Power's new Twisted Steel header delivers an astounding 12hp and 19lbs. x ft. torque while outflowing the factory exhaust manifold. aFe engineers have designed a header that features a symmetrical tube design for optimum balance and efficiency of exhaust flow. 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% 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
