The present invention relates to a secondary air injection system for an internal combustion engine, and an automotive vehicle comprising such a secondary air injection system. The arrangement includes shut-off valve for selectively passing on or restricting airflow form the secondary air injection system. A flexible connector is arranged to receive the airflow and pass it on to at least two reed-type non-return valves arranged to substantially only allow airflow in the downstream direction. At the downstream side of each respective reed-type non-return valve a conduit for communicating any airflow passed there through to an associated exhaust bank of the internal combustion engine.
