Abstract
Exhaust system for multicylinder internal combustion engines comprises an exhaust gas manifold with an arrangement consisting of exhaust gas pipes and at least one exhaust gas catalyst (3) branching in the direction of the engine and connected on one engine side to its exhaust gas outlet openings. The exhaust gas outlet side of the branched exhaust pipe arrangement is formed by two adjacent gas outlet openings, each flow-connected to one part of the branched exhaust pipes and to which is connected a pipe (13', 13'') of a double pipe arrangement (13) having two parallel pipes. The other gas outlet side end opens into a flow sleeve (16) arranged in front of the exhaust gas catalyst. Preferred Features: The double pipe arrangement is guided up to just before the lambda sensor (17) of the exhaust gas catalyst and/or the lambda sensor is arranged in the flow sleeve.
