Patterned after our already popular and dyno-proven Mega-power Headers, which have been used by leading, competitive race teams for years, Skunk2’s Alpha Header employs many of the same design characteristics and technology. Our decision to produce the Alpha Header was driven by our desire to make our race-proven design more affordable and accessible to everyday enthusiasts. New manufacturing techniques allow us to do so at a lower overall cost, making race-winning header technology available to everyone.

The first Alpha Header to be released will be for the 06-11 Civic Si.These headers have the exact same specs and dimensions as our Mega-power header, so they will make the exact same power. They are also both made out of the same T304 Stainless Steel.

 

All Skunk2 headers are designed and engineered to maximize exhaust flow and increase both horsepower and torque throughout the power-band. 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’s unique design specs, provide an extremely broad power-band that’s 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 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 Alpha Series Header provides the perfect combination of top-end power without sacrificing mid-range performance or throttle response.
