Abstract
An exhaust manifold for a multicylinder type internal combustion engine has a connector is employed for connecting downstream ends of gas conduits to upstream ends of a forked exhaust pipe. The connector is of a monolithic casting and comprises a base plate portion having openings respectively connected to the upstream ends of the forked exhaust pipe, two collar portions intergrally formed on the base plate portion and having respective bores merged with the openings of the base plate portion respectively. The downstream ends of the gas conduits are sealingly received in the collar portions. A sensor mount is integrally formed on the connector for mounting a gas sensor. The sensor mount has a bore which is exposed to the interior of both the two collar portions.
