Abstract
At least one of the ends of the silencer an end chamber is defined between an intermediate planar dished wall and an end dished wall which is provided with a rounded and hollow boss. The boss substantially extends two exhaust gas tubes in front of which it is located and its apex is spaced from the intermediate dished wall by a distance which is slightly greater than the radius of the tubes so that the boss guides the change in direction of the gas flow between the tubes.
