Product Description

Skunk2 is proud to introduce its MegaPower Header for Honda's K-series engines, specifically designed for engine swaps. Skunk2 has been designing custom headers for its drag racing, road racing, and endurance cars for years, and is now offering this same technology to consumers. Skunk2’s engineers wanted to offer the same custom racing headers they use on the company’s own cars to enthusiasts at a good value, but without compromising quality. The process has taken years, but thanks to cutting-edge design, manufacturing technology, and craftsmanship, Skunk2’s produced the finest production header available. MegaPower Headers power each of the championship-winning, Compass 360 Racing Grand-Am Cup Hondas and Acuras. In a class where competitors are not allowed to modify intakes and ...

Skunk2’s MegaPower Header is designed and engineered to maximize exhaust flow and increase both horsepower and torque throughout the powerband. The unique design is the result of more than a decade of racing experience coupled with computerized modeling and extensive dyno testing. Each Skunk2 MegaPower Header features equal-length, sequentially paired, stepped primaries and a 4-2-1 tri-Y design that terminates into a collector with a 2.5" outlet. These features, paired with Skunk2’s unique design specs, provide an extremely broad powerband that’s applicable to a wide range of engine sizes and configurations. MegaPower Headers also feature the smallest possible primary tubes required to achieve optimum overall and peak power. By minimizing the primary tubes’ diameter, Skunk2 is able to maintain the highest possible exhaust gas speed throughout the header, which improves mid-range power and throttle response significantly. Skunk2’s MegaPower Header provides the perfect combination of top-end power without sacrificing mid-range power or throttle response.

Compare Skunk2’s MegaPower Header against the competition and you’ll see the difference. Each MegaPower Header’s finish, weld consistency and color, fitment, and kit completeness remains unparalleled. MegaPower Headers are welded after being polished so users can see each weld’s quality and color. Other manufacturers polish their welds to disguise the oxidation that results from improper welding temperatures and poor gas shielding. Skunk2 headers are also back-purged and welded by expert craftsmen. All of this is evident by the evenly spaced, light gold colored welds, each with slight blue highlights. Each header is constructed from T-304 stainless steel with fully polished, mandrel-bent tubing and a CNC-machined flange for added strength and durability. [Read less ↑]
