Abstract
A mixer assembly for a vehicle exhaust system includes a mixer housing defining an internal cavity that is configured to receive engine exhaust gases and an upstream baffle that is positioned at an inlet end of the mixer housing. The upstream baffle comprises a plate having an open area that comprises a fixed geometric configuration through which exhaust gas enters the internal cavity. A valve is movable from a closed position toward an open position to provide a variable geometric configuration that changes the open area to reduce back pressure.
