Zusammenfassung:	An exhaust by-pass system in an internal combustion engine provided with a turbocharger. The turbocharger is the so-called twin entry type having a pair of scroll passageways connected to two groups of cylinders of the engine, respectively. By-pass passageways are formed in a housing of the turbine of the turbocharger. The by-pass passageways are connected to scroll passageways, respectively at positions near their inlets. The by-pass passageways are opened or closed by a common by-pass control valve arranged in a tubular boss portion of the housing.
