Skunk2 is proud to introduce its Alpha Series Header for the â€™02-â€™06 DC5 and â€™02-â€™05 Civic Si. Patterned after our already popular and dyno-proven MegaPower Headers, which have been used by leading, competitive race teams for years, Skunk2 Alpha Series Header employs many of the same design characteristics and technology. Skunk2 engineers wanted to offer the same custom racing headers they use on the company 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 produced the finest production header available. Similar 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 throttle bodies, the header and exhaust system become the keys to finding additional power.
All Skunk2 headers are 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 Alpha Series 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-inch outlet. These features, paired with Skunk2 unique design specs, provide an extremely broad powerband that applicable to a wide range of engine sizes and configurations.
Alpha Series Headers also feature the smallest possible primary tubes required to achieve optimum overall and peak power. By minimizing the primary tubesâ€™ 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 Alpha Series Header provides the perfect combination of top-end power without sacrificing mid-range performance or throttle response.
Skunk2's Alpha Series Header for the DC5 is designed to clear the OEM anti-sway bar (K24 engines require downward-hoop-type anti-sway bar) and is compatible with most aftermarket exhaust systems that bolt to the factory location using factory mounting points (MegaPower RR Exhaust requires fabrication of supplied header adapter).
