Various systems and methods are provided for routing exhaust from an engine. In one example, a system includes a high pressure turbine and a low pressure turbine. The system further includes a first passage for routing exhaust from a first subset of cylinders, bypassing the high pressure turbine, to upstream of the low pressure turbine in an exhaust passage of the engine, and a second passage for routing exhaust from a second, different, subset of cylinders to upstream of the high pressure turbine. |
