A modular engine manifold construction comprising a series of cast metal headers, each having an inlet communicating with an exhaust gas port in the engine. Each header is also provided with a passage that extends through the headers and is located generally normal to the inlet. Stainless steel tubes are slidably mounted within the aligned passages and interconnect the headers. The ends of the tubes are provided with longitudinally extending slots which engage locating pins on the inner surface of the headers to prevent rotation of the tubes, yet permit longitudinal movement of the tubes relative to the header to accommodate heat expansion. The ends of the tubes are also provided with cut-out sections or notches which are aligned with the inlet in the header when the slots in the tubes are engaged with the locating pins. The assembled manifold is a non-welded construction formed of a minimum number of component parts.
