Skunk2’s Alpha Series Header for the ND Miata was engineered from the beginning to increase both horsepower and torque throughout the powerband. The maximized exhaust flow is accomplished through specifically tuned header tubes formed into a 4-1 design that terminates into a True Merged collector with a 2.5-inch outlet. This refined design was the result of more than a decade of racing experience coupled with computerized modeling and extensive dyno testing. These features, paired with Skunk2’s unique design specs, provide an extremely broad powerband that applies to a wide range of engine sizes and configurations. Alpha Series Headers also feature bung provisions for OEM sensors. Each header is constructed from T-304 stainless steel with mandrel-bent tubing for added strength, corrosion resistance, and durability.
