Abstract
A silencer for the exhaust gas of motor vehicle internal combustion engines is proposed comprising an outer wall having in its upper part a deformable zone, preferably in the form of a transverse indentation, which provides preferential deformation under impact, and if a rear impact occurs prevents the silencer from rigidly striking the most inner structure of the vehicle floor and the fuel tank.
