Layout structure of catalytic converters

A layout structure of catalytic converters for a V-type engine transversely arranged in an engine room formed in a front portion of a vehicle, comprising

• a front catalytic converter connected to an exhaust manifold arranged in a forward direction of said vehicle with respect to said engine, and a rear catalytic converter connected to an exhaust manifold arranged in a backward direction of said vehicle,
• wherein said rear catalytic converter is formed into a cylindrical member having an elliptic/oval cross-sectional shape with a major axis coinciding with a longitudinal direction of said vehicle.
