The exhaust manifold found on the 1988-2000 Honda civic and crux d15/d16 sohc 4 cylinder engines 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 1.5l and 1.6l engines. 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./88-00 Honda civic d-series sohc/88-91 Honda crux d-series sohc/93-97 Honda del sol d-series sohc.
