Alpha Series 4-2-1 Stainless Steel Header

The Skunk2 Racing Alpha Series Header is engineered to deliver enhanced performance by optimizing exhaust flow, resulting in increased horsepower and torque across the entire powerband. This unique design terminates into a 2.5-inch collector, minimizing primary tube diameter to maintain high exhaust gas velocity for improved mid-range power and throttle response without sacrificing top-end performance. Constructed from durable T-304 stainless steel with mandrel-bent tubing and a polished finish, this header is built for longevity and corrosion resistance. It is designed for K-series engine swaps in a range of Honda Civic (1988-2000) and Integra (1990-2001) models. A key benefit of the Alpha Series Header is its fitment; it does not require cutting or modifying the front cross-member and is compatible with common K-swap mount kits like Hasport. Specifically, this header is designed for clearance with the Kraftwerks Supercharger Kit and is suitable for B-series V2 applications. It also includes O2 bungs for OEM and aftermarket sensors. For applications with certain supercharger kits, such as the Kraftwerks B-Race Kit, modifications to the exhaust or a test-pipe may be required for proper clearance and fitment.
