Abstract

In order to provide a silencer (100), in particular an exhaust silencer, for an internal combustion engine, comprising a first housing (12) with an inlet aperture (E) and an outlet aperture (A), wherein an exhaust stream flowing into the inlet aperture (E) and escaping from the outlet aperture (A) is fed via a catalytic converter element (K), which silencer can be variably used for various internal combustion engines of different engine displacement, which silencer achieves low final temperature values, low sound values, and small pressure fluctuations and in addition allows a space-saving exhaust-flow guide arrangement through the silencer, it is proposed that a calming chamber (10) be provided between an outlet area (30) of the catalytic converter element (K) and the outlet aperture (A) of the first housing (12).
