Abstract
An exhaust system for internal combustion engines, in particular two-cycle internal combustion engines, includes a resonance-type exhaust part having at least one diffuser-cone unit formed with a diffuser, a countercone, and a connecting part with a preferably constant cross section extending between the diffuser outlet cross section and cone inlet cross section. In order to provide the resonance-type exhaust part as compact as possible by employing a simple production method, the connecting part is formed as a first deflection arc, preferably with an angle of deflection of about 180°±30°.
