Abstract
A motorcycle exhaust system includes a catalytic converter () disposed within an exhaust passage () for discharging exhaust gas (G) from a multi-cylinder combustion engine (E) and operable to purify the exhaust gas (G). An upstream end of the catalytic converter () has different regions (Sand S) communicated with upstream exhaust passage portions (and), respectively, and a downstream end of the catalytic converter () is communicated with downstream exhaust passage portions (and) in a number equal to or smaller than the number of the upstream exhaust passage portions (and). Also, the catalytic converter () has a partition wall () extending in a direction of flow of the exhaust gas (G) for allowing the exhaust gas (G) from the upstream exhaust passage portions (and) to flow through the catalytic converter () without being mixed together.
