摘要：
The present invention relates to an exhaust system (10) comprising: an exhaust conduit (11), connectable to an engine (30) of a vehicle for discharging of exhaust; a first catalyst (12) disposed in the exhaust conduit (11) for purifying the exhaust gas; a secondary air supplying conduit (16) connected to the exhaust conduit (11) in a connecting position provided more upstream than the first catalyst (12) for supplying secondary air to the exhaust gas in the exhaust conduit (11); a sensor (14) for detecting an air-fuel ratio in the exhaust conduit; wherein the sensor (14) is mounted on a part of the exhaust conduit (11) more downstream than the connecting position (11e) of the secondary air supplying conduit (16) and more upstream than the first catalyst (12).
