A motor vehicle has an internal combustion engine and an exhaust system with an exhaust which has two deformable pipe members and at least two casings arranged downstream thereof and belonging to a catalytic converter and/or silencer. At least the last casing, relative to the direction of flow of the exhaust gas, of the exhaust, together with the first casing, defines a straight connecting line passing through the two casings and is held on the vehicle body by means of at least partially rubber-elastic connecting members in such a way that it is deflected by a force parallel to the straight connecting line more than by a force of equal magnitude at right angles to the straight connecting line. This enables the casings to be connected to one another exclusively by rigid exhaust parts and oscillations of the second casing to be kept small.

[ What is claimed is:] [1.] An exhaust system for a motor vehicle having a vehicle body, an internal combustion engine, and an exhaust which can be connected to the internal combustion engine, the exhaust system comprising at least one deformable pipe member, and at least two casings arranged downstream of said deformable pipe member and having retaining means for holding the exhaust on the vehicle body, the first casing being arranged downstream of the deformable pipe member, and the last casing defining a straight line passing through the two casings,wherein the exhaust has an exhaust section which connects the first casing to the last casing and is essentially rigid along its entire length,wherein each of said casings comprises a shell having a wall thickness of at most 1 mm,wherein the exhaust section connecting the first casing to the last casing comprises at least one pipe having a wall thickness of at most 1 mm,wherein each casing has two opposite ends,wherein the retaining means have two holders for holding the exhaust in the vicinity of the opposite ends of the casings, and have elastically deformable connecting members, andwherein connecting members which are associated with the last casing are elastically deformable in such a manner that in a state separated from the remaining exhaust, the last casing is adapted to be deflected, relative to the vehicle body, a greater distance by a force acting on said last casing and parallel to said straight line than by a force of equal magnitude acting on said last casing and at a right angle to said straight line.
