Abstract

A catalytic exhaust device for motorcycle (1) in which the exhaust device comprises exhaust pipes separately connected to the cylinder exhaust holes of V-shape engine and the exhaust pipes extend backwards; meanwhile, the exhaust pipes merge at down stream side and the merged stream is connected to the muffler; which is characterized in that a main catalyst traversing the exhaust pipes is installed at the mergence place of the exhaust pipes and auxiliary catalysts are separately installed on the exhaust pipes prior to the mergence place so as to minimize the temperature difference among the exhaust in the exhaust pipes in order to stabilize the exhaust temperature at the mergence place.
