Abstract: Disclosed is an exhaust manifold for engaging with a plurality of exhaust ports of a multi-cylinder engine for guiding an exhaust gas discharged out of from the multi-cylinder engine. The exhaust manifold includes a plurality of primary conduits and a secondary conduit. Each of the primary conduits includes inlet and exit end portions. Each of the inlet end portions is capable engaging with a corresponding exhaust port. The secondary conduit includes at least one inlet port and at least one exit port. The exit end portions of each of the primary conduits converges with the at least one inlet port to configure a passageway. With the convergence of each of the exit end portions port with the at least one inlet port, there is gradual increase in a cross sectional area of the passageway for guiding the exhaust gas to be discharged out from the multi-cylinder engine.
