The Skunk2 MegaPower Header for 2006-2010 Honda Civic Si is designed and engineered to increase both horsepower and torque throughout the powerband while maximizing exhaust flow. The unique design of the Skunk2 Megapower Header is the result of computerized modeling, extensive dyno testing and more than a decade of racing experience. Each Skunk2 MegaPower Header features sequentially paired, stepped primaries, equal-length tubing and a 4-2-1 Tri-Y design that collects into a 2.5-inch outlet. MegaPower Headers also feature the smallest possible primary tubing required to achieve peak power. By minimizing the primary tube diameter, Skunk2 is able to maintain the highest possible exhaust gas speed throughout the header. This speed improves throttle response and mid-range power significantly. The Skunk2 Megapower Header provides the perfect combination of mid-range power and throttle response without sacrificing top-end power on the 2006-2010 Honda Civic Si.
