ABSTRACT OF THE DISCLOSURE The exhaust manifold for a transversely mounted automobile engine terminates adjacent to the negine in an outlet having an articulated connection with the inlet of an exhaust header that terminates in an exhaust pipe discharging to the atmosphere. The articulated connection comprises an annular coupling portion having a spherical surface at the header inlet seated in sealing engagement with a spherical or conical sealing surface de- fining the manifold outlet. An annular flange adjacent to the inlet of the header may be seated in sealing engagement against a second sealing surface of the annular coupling portion. The sealing engage- ments may be maintained by a collar yieldingly urged against the annular flange by spring means that engage the collar at spaced locations on a line parallel to the roil axis of the engine and passing through the center of the first named spherical surface. Exhaust tuning is accomplished by partitioning the header inlet into separate exhaust passages that communicate with selected exhaust ports of the engine by means of short conduits of the manifold. At a predetermined location downstream of the exhaust ports, the separate passages of the header merge.
