A silencer for the exhaust systems of internal combustion engines is designed to provide controlled expansion of the gases to minimise noise. The box section silencer (1) is designed with an inlet pipe (4) that projects up to one half the length of the box. An output pipe (7) is of slightly larger diameter than the inlet and projects some three quarters of the box length. The inlet has a number of small diameter holes (5) and a reduced diameter end section (6). The outlet pipe has a flared end (8).
