DNA motoring HDS-HA90-41 Stainless Steel 4-1 Header Exhaust Manifold

The exhaust manifold found on the 1990-1993 Honda accord f22b 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 tri-y 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 2.2l 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. / This item fits: 90-93 Honda accord 2.2l l4 sohc.
