A turbocharger for a use with a combustion engine is provided. The turbocharger may have a turbine housing with a first volute, a second volute, and a common outlet. The turbocharger may also have a turbine wheel disposed between the common outlet and the first and second volutes. The turbocharger may further have a first valve configured to selectively fluidly communicate the first volute with the second volute upstream of the turbine wheel, a second valve configured to selectively fluidly communicate the second volute with the common outlet to bypass the turbine wheel, and a common actuator configured to move the first and second valves.
