Abstract
In order to prevent the formation of a standing wave in the exhaust system one or more small transfer passages are formed either inthe body of the manifold or in the cylinder head. These passages permit exhaust pressure to be transmitted to the exhaust ports of the adjacent cylinders as well as into the exhaust conduiting. This destructively interferes with the formation of the standing wave and thus obviates the generation of exhaust noise.
