Abstract

The simple additional silencer is intended for use with a main silencer in a vehicle exhaust system. The two exhaust system. The two exhaust pipes (11, 1r) pass through a silencer casing (2) each pipe having an opening (5) within the confines of the casing. A very effective damping of low-frequency noise is possible when the casing interior is divided by a partition (3) into two chambers (41, 42) with which the openings are connected by leads (6) each opening into the end (77, 72) of a respective chambers.
