FIELD: transport engineering; exhaust systems of internal combustion engines. SUBSTANCE: invention relates to exhaust systems of vehicles powered by internal combustion engines with forced ignition of working mixture in which exhaust gases are let out through two separate subsystems at least on separate sections of exhaust system. Each subsystem has at least one catalyst converter with axial channels. Catalyst converter is made in form of common cellular member provided with at least one partition at one end face side dividing housing along its cross section and tightly getting to end face side of cellular member, thus providing gas tightness. EFFECT: provision of simple to manufacture catalyst converter suitable for letting out separate flows of exhaust gases. 26 cl, 5 dwg
