2006-2011 Honda Civic Si Skunk2 Megapower Header

The Skunk2 MegaPower Header is designed and engineered to maximize exhaust flow and increase both horsepower and torque throughout the entire RPM powerband. Our unique design is the result of over 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 with a 2.5 inch collector. These features coupled with our unique design specs provide an extremely broad powerband that can be used on a wide range of engine sizes and configurations. 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.
