Methods and systems are provided for a branch communication valve in a twin turbocharger system. A branch communication valve may be positioned adjacent to a dividing wall separating a first scroll and a second scroll of the twin turbocharger. In an open position, the branch communication valve increases fluid communication between the first scroll and the second scroll and in a closed position, the branch communication valve decreases fluid communication between the first scroll and the second scroll.

Methods and systems are provided for exhaust leak management in an engine. The exhaust leakage management system may include a port disposed to capture leaked exhaust along a movable portion associated with a turbine. The exhaust leakage management system may also include a three-way valve at a bifurcation of the port, directing leaked exhaust either to a first passage fluidically connected to a crankcase of the engine or to a second passage fluidically connected to a downstream portion of an exhaust pipe, depending on engine operating conditions.
