Abstract
An exhaust manifold for at least a portion of an internal combustion engine having a defined number of combustion chambers includes a plurality of inlet ports and four outlet ports. A first pair of the four outlet ports are disposed in gas flow communication with a first subset of the plurality of inlet ports, and a second pair of the four outlet ports different from the first pair are disposed in gas flow communication with a second subset of the plurality of inlet ports different from the first subset.
