TEGIWA Honda S2000 Race Manifold Header. At last... the long awaited manifold has arrived! Changing the manifold is one of the best modifications you can do to your S2000. Just with this alone gains of between 2-5bhp are achievable before mapping and after mapping with complimentary mods between 7-10bhp. Constructed from premium 304 grade Stainless steel.
It features the popular 4-2-1 design, CNC mill-cut flanges & robotic rotation purge TIG welding. Being a 4-2-1 configuration means it gives great gains throughout the rev range. The primaries are 51mm OD and the collector flange is 63mm OD.
Please note: this is a direct fit unlike ALL manifolds from the USA.
