An exhaust gas module comprising of a housing (12), at least one inlet (14) of the housing, a plurality of outlets (16a,16b) in the housing, and a valve (18) inside the housing, wherein exhaust gas passes through an EGR path (36) when directed to a first outlet. A single actuator is used to control the valve. The primary valve directs the flow of exhaust gas with respect to the EGR path, and when the EGR path is substantially open, the actuator alters the position of the valve to close the-exhaust path to increase the back pressure in the inlet and housing in order to increase the flow of exhaust gas through the EGR path.
