Abstract: An exhaust system includes an exhaust manifold structured to be fluidly coupled to an engine. A turbocharger including a turbine housing is fluidly coupled to the exhaust manifold. An exhaust pulse converter includes a first portion integral to the exhaust manifold and a second portion integral to the turbine housing. The exhaust pulse converter is structured to reduce engine pumping losses by reducing cross-talk of exhaust blowdown events from the engine.
