Abstract
An adaptive valve assembly includes a pipe defining a passageway for conducting engine exhaust gases, a pivot shaft supported by the pipe, and a valve body coupled to the pivot shaft. The valve body is moveable between an open position where exhaust gas flow through the passageway is increased and a closed position where exhaust gas flow through the passageway is reduced. A resilient member biases the valve body toward the closed position. A retainer assembly includes at least one damping feature that engages the resilient member to dampen vibrations.
