The Megan Racing MR-SSH-HC8800SI is a high-performance exhaust header engineered for the 1999-2000 Honda Civic Si models equipped with the B16A DOHC engine. Its 4-1 equal-length primary tube design is optimized to enhance the VTEC crossover, contributing to improved power delivery. The header also features a larger 2.25-inch collector, which promotes better exhaust flow. Constructed from durable T-304 stainless steel, the piping is mandrel-bent to ensure smooth transitions and minimize restrictions. The flanges are precisely laser-cut for a perfect fit. The header boasts a polished finish for a show-quality appearance and is designed as a direct bolt-on replacement. Installation of this header is recommended to be performed by a professional. Please note that this product is intended for off-road use only. It is crucial to check local exhaust regulations before proceeding with installation to ensure compliance.
