ABSTRACT:
An exhaust system of a transverse V-type or horizontal opposed type engine having front and rear cylinder banks includes: front and rear exhaust pipes which are respectively provided for the front and rear cylinder banks; front and rear catalytic converters which are respectively connected to the front and rear exhaust pipes; a joint exhaust pipe which is connected to the front and rear catalytic converters for collecting exhaust gas from the front and rear catalytic converters; and a combined exhaust pipe which is connected to the joint exhaust pipe. The combined exhaust pipe has a longitudinal axis which is substantially parallel to a longitudinal axis of the rear catalytic converter such that exhaust gas flow in the rear catalytic converter is in the substantially opposite direction to exhaust gas flow in the combined exhaust pipe. Each of the front and rear catalytic converters has an elliptical section. A major axis of the elliptical section of the rear catalytic converter is inclined at a certain angle relative to the combined exhaust pipe.
