The motor vehicle exhaust gas system has a valve system consisting of a tubular housing (1) in which a flap (2) attached to a shaft (5) regulates the exhaust gas passage. The housing has a collar (3) at a non-uniform distance from the central axis of the housing on which the flap rests in the closed position. The flap shape deviates slightly from the circular.
