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 Skunk2s unique design specs, provide an extremely broad power-band thats 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. Skunk2s Alpha Series Header provides the perfect combination of top-end power without sacrificing mid-range performance or throttle response. Applications:06-11 Honda Civic SiNote: Complement with a genuine Skunk2 MegaPower R Exhaust system for maximum exhaust flow and gain.
