Abstract
An automotive engine is generally provided with an exhaust gas pipe assembly extending generally rearwardly from the engine for discharging exhaust gases. The exhaust gas pipe assembly includes a plurality of exhaust gas pipes, at least one chamber formed intermediately of the exhaust gas pipe assembly, a first support member disposed in the proximity of the engine, and at least one second support member disposed in the proximity of the chamber. The first support member can effectively absorb relative displacement between the exhaust gas pipe assembly and the vehicle body in a direction transversely of the vehicle body whereas the second support member can effectively absorb relative displacement between the exhaust gas pipe assembly and the vehicle body in a direction longitudinally of the vehicle body. The exhaust gas pipe assembly further includes a dynamic damper disposed in the proximity of the second support member for reducing vibration of the exhaust gas pipe assembly in directions generally perpendicular to the direction longitudinally of the vehicle body.
