Tri-Y Exhaust Header for B16/B18

The Skunk2 Racing Alpha Series Header V1 is a performance-oriented exhaust manifold engineered for Honda B-Series engines. Constructed from durable T-304 stainless steel, this header is built to withstand demanding conditions. The primary tubes are designed with a small diameter to ensure optimal exhaust gas velocity, and the 2.5-inch outlet collector further contributes to performance gains. Please note that this header is intended for race applications and eliminates the catalytic converter. It requires custom fabrication of a test-pipe to connect with standard cat-back exhaust systems and is not compatible with OEM catalytic converters without modification. For installations on Type R engines, adjustments to the transmission stiffener are necessary. The Skunk2 Alpha Series Header is compatible with the following vehicles: 1990-2001 Acura Integra, 1999-2000 Honda Civic Si, and 1994-1997 Honda Del Sol VTEC.
