4-2-1 45mm Stainless Steel Exhaust Manifold, F22C

The Mugen exhaust manifold is a performance-oriented header specifically engineered for the Honda S2000 AP2 models from 2004 to 2009, featuring the F22C engine. Mugen conducted extensive dynamo testing to develop an optimal layout, changing the primary length and collection point compared to the F20C exhaust manifold. This optimization results in significant improvements in both power and torque across the entire engine speed range, from low to high RPMs, providing more accessible and usable engine characteristics. Constructed entirely of stainless steel, this JASMA certified manifold meets all safety standards and comes equipped with a heat shield. It offers a substantial weight reduction, weighing in at 6.2kg compared to the stock manifold's 10.2kg, contributing to overall vehicle performance. This exhaust manifold is designed as a direct fit for the S2000 AP2 (2004-2009) with the F22C engine, including specific models AP2-100 and AP2-110.
