The system comprises an exhaust gas recirculation manifold arranged to distribute recirculated exhaust gas in an intake air stream to be introduced into the combustion engine; wherein the manifold has an exhaust gas recirculation inlet and an intake air inlet as well as at least one outlet leading to the multiple cylinders of the engine. The system also comprises a first distribution pipe, which has a first pattern of flow distribution perforations for distributing the recirculated exhaust gas into the manifold. The system further includes a second distribution pipe with a second pattern of flow distribution perforations for distributing the recirculated exhaust gas into the manifold, and at least one of the first and second distribution pipes being rotatable with respect to the other.
