Abstract
An exhaust pipe assembly for a multi-cylinder internal combustion engine is made up of a plurality of exhaust pipes made of steel whose upstream ends are connected to a flange provided for connection to a cylinder head, a collecting case to which downstream ends of the exhaust pipes are connected, and a coupling flange interposed between the exhaust pipes and the collecting case. The coupling flange is made of a thin steel plate and has upward burred portions which are circular in shape and into which respective downstream ends of the exhaust pipes are separately inserted for welding with the burred portions, and a downward bent portion whose peripheral edge portion is fitted onto an upper outside end portion of the collecting case for welding with the bent portion.
