Methods and systems are provided for expediting catalyst warm-up. In one example, a method may include flowing exhaust gas from an engine first through an emission control device and then through a turbine to rotate the turbine in a reverse direction, the rotation of the turbine in the reverse direction generating intake manifold vacuum for a vacuum consumer via a compressor coupled to the turbine. In this way, heat loss through a turbine may be avoided.
