421 Stainless Steel Exhaust Manifold

The Spoon Sports 421 Exhaust Manifold is a high-performance exhaust header set engineered to optimize torque and power output for naturally aspirated Honda engines. This 4-2-1 design facilitates improved exhaust gas scavenging, contributing to enhanced engine performance. Constructed from durable stainless steel, this manifold is significantly lighter than its factory counterpart, weighing in at 6.8 kg compared to the OEM weight of 11.5 kg. The 4-2-1 configuration is a key design element intended to maximize performance gains. Compatibility is strictly limited to Type-R models. The Spoon Sports 421 Exhaust Manifold is designed for the following specific applications: Honda Civic Type-R EK9 with B16B engine (produced between August 1997 and August 2000), and Honda Integra DB8 and DC2 with B18C engine (produced between July 1993 and July 2001). Fitment is guaranteed for JDM (Japanese Domestic Market) vehicles only, and buyers are advised to conduct their own research to confirm compatibility with non-JDM applications.
