ABSTRACT OF THE DISCLOSURE An exhaust manifold for a multi-cylinder engine employs three concentric exhaust reaction chambers. Exhaust inlet pipes convey hot exhaust gases from the exhaust ports of the engine directly into the innermost reaction chamber. The concentric reaction chambers extend substantially at right angles to the exhaust inlet pipes which are parallel. Concentric tubes encircle the exhaust inlet pipes and each is connected to one of the concent- ric exhaust chambers. The flared portions of the exhaust inlet pipes engage in surface contact with the correspondingly flared portions of the tubes. End members having concentric shoulders engage cylindrical shells which defines the exhaust reaction chambers. Bolted spacers are positioned substantially midway of the length of the shells and space them in concentric fashion.
