This K24 swap header is engineered specifically for the 2000–2009 Honda S2000 chassis, offering proven performance with true bolt-in fitment. The 4-2-1 design closely matches the overall dimensions of the factory S2000 header, ensuring compatibility with stock and common aftermarket exhaust systems.

Constructed from 16-gauge 304 stainless steel, the header features 1.75-inch primary runners stepping to 2.25-inch secondaries, a 2.5-inch collector, and a 3-inch V-band outlet. It uses our preferred cylinder pairing of 1–4 and 2–3 to promote effective exhaust scavenging and strong midrange power.

Dyno proven and built for both street and track use, this header delivers reliable performance without compromising fit or serviceability.

This header has been extensively tested for a full season of Gridlife GLTC on an ASM Race S2000, ensuring the durability and longevity of every component, bend, and weld.
