Beschreibung
Zusammenfassung:	A valve assembly for an exhaust system of a vehicle. The valve assembly includes a housing, a valve flap and a mass damper. The housing defines an inlet, an outlet, and a longitudinally extending exhaust gas passageway in fluid communication with the inlet and the outlet. The valve flap is disposed in the housing and is rotatable between a first position restricting exhaust gas flow through the exhaust gas passageway, and a second position whereat exhaust gas flow through the exhaust gas passageway is less restricted. The mass damper is disposed within the exhaust gas passageway. The mass damper is attached to the valve flap and comprise of a material having a high density. The mass damper is shielded from the exhaust gas flowing through the exhaust gas passageway when the valve flap is in the second position.
