A motor vehicle exhaust system, including at least one pollutant-removing member, for example a catalytic converter or a particle filter, including a first outlet and connected to an exhaust line of an associated vehicle, and a second outlet for collecting exhaust gases with a view to recycling the same, the second outlet being connected to an inlet pipe of an exchanger for cooling exhaust gases, an outlet pipe of which is connected to a housing that receives a valve for controlling exhaust gases. The housing of the control valve includes a sole plate to be attached to an end sole plate of the outlet pipe of the exchanger, and the housing is attached directly onto a body of the exchanger.

A supercharger arrangement for an engine assemblyis disclosed, the arrangement including first and second superchargersA,B that are mounted on the engine assembly by means of separate first and second mounting membersrespectively. Each mounting member defines an integrated supercharger lubrication conduitA,B,A,B and the present invention is characterized in that the superchargersA,B are of substantially identical construction and are separable from the first and second mounting members. The integrated lubrication conduitsA,B,A,B are routed through their respective said mounting members in such a manner as to enable the first and second superchargers to be mounted on the engine assemblyin substantially mirror image orientations thereabout.
