Skunk2 Alpha Series Header for 02-06 RSX

Skunk2 Alpha Series Header – 2002-2006 Acura RSX Base & Type S

Unlock the full performance potential of your 2002-2006 Acura RSX Base and Type S with the Skunk2 Alpha Series Header. Engineered with race-proven technology, this high-performance header is patterned after Skunk2’s world-renowned MegaPower Headers, trusted by championship-winning race teams. Designed to maximize exhaust flow, the Alpha Series Header delivers noticeable gains in horsepower, torque, and throttle response across the entire RPM range.

Featuring a 4-2-1 Tri-Y design, equal-length stepped primaries, and a precision-engineered 2.5-inch collector, the Skunk2 Alpha Series Header improves exhaust velocity while maintaining optimal mid-range power. By utilizing the smallest possible primary tube diameters for efficiency, this header balances top-end performance with strong mid-range drivability, making it ideal for both street and track use.

Constructed with advanced manufacturing techniques and decades of racing experience, the Alpha Series Header is designed to clear the OEM anti-sway bar (K24 swaps require a downward-hoop-style sway bar) and bolt up to most factory-style and aftermarket exhaust systems. For maximum performance, it pairs perfectly with a Skunk2 MegaPower Exhaust.
