Abstract
A passive valve assembly for a vehicle exhaust system includes an exhaust component that defines an exhaust gas flow path and a vane that is positioned within the exhaust gas flow path. The vane is positioned at an initial start position and is movable between a closed position to provide a minimum exhaust gas flow and an open position to provide a maximum exhaust gas flow. The start position is orientated at a negative angle relative to the closed position.
