Abstract
A vehicle mounted internal combustion engine has a dual exhaust system including a single manifold having separate plenums connected to receive exhaust from diverse ones of the engine cylinders. The plenums have separate concentrically arranged discharge fittings which connect with a pair of exhaust pipes, mounted one inside the other, to provide two separate exhaust flow paths from the engine cylinders to the ends of the manifold connected exhaust pipes at their juncture with an associated exhaust converter.
