Abstract
An exhaust structure for an exhaust manifold associated with an engine includes a first inlet section that defines a first inlet flow passage configured to receive exhaust gas, the first inlet flow passage defining a normalized cross-sectional area of flow, a second inlet section that defines a second inlet flow passage configured to receive exhaust gas, the second inlet flow passage defining the normalized cross-sectional area of flow, and an intermediate section disposed between the first inlet section and the second inlet section and in fluid communication with each of the first inlet section and the second inlet section, the intermediate section including: a flange and an exhaust redirection section having a reduced cross-sectional flow path measured at a midpoint along a length of the flange that is less than the normalized cross-sectional area of flow of the first inlet flow passage.
