This cast-iron exhaust port divider is designed to correct the flow of No. 3 and No. 4 exhaust port to equal that of the other cylinders. In dividing the flow channels, they cancel out the negative effect of exhaust from each cylinder flowing against each other. By doing so each cylinder produces an equal amount of power at all RPM points, thus an increase of as much as 10% can be gained.
