TRI-Y B16/B18 4-1 HEADER EXHAUST MANIFOLD FOR CIVIC SI EM1/DC1 DC2 GSR/TYPE-R

 

ITEM SKU: KOS-HDS-HC88-B18-41

 

This exhaust manifold for the 1990-2001 Acura Integra 1.6L and 1.8L DOHC 4 Cylinder Engine were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-1 off-road racing headers are designed to allow the exhaust gasses to flow more freely from each cylinder and combine in a more efficient manner. Tubing has been optimized for the 1.6L and 1.8L engine. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.
