The invention relates to a silencer for an exhaust system of an internal combustion engine of road vehicles preferentially. The silencer has a housing in which an expansion chamber is formed; an inlet pipe feeding exhaust gas into the housing and including an end part in the housing and an outlet opening in the expansion chamber; a main outlet pipe leading the exhaust gas out of the housing; and a secondary outlet pipe leading the exhaust gas out of the housing and including an inlet opening in the expansion chamber. When the main outlet pipe in the housing includes an initial section protruding into the end part of the inlet pipe and a gap is formed in an overlapping area between the end part of the inlet pipe and the initial section of the main outlet pipe, improved acoustic feedback is obtained. A bypass which bypasses the initial section of the main outlet pipe is formed in the end part of the inlet pipe. The exhaust gas can flow through the bypass from the inlet pipe into the expansion chamber.
