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 cooperates with the resilient member to define a valve stop for the valve body when in the closed position.
