ABSTRACT:
An engine exhaust system for a vehicle is provided in which it is possible to obtain necessary vibration damping performance even when there are layout restrictions. For instance, a spherical joint on a front side of the vehicle and a spherical joint on a rear side of the vehicle, are positioned before and after two catalysts, and the components positioned between the front and rear spherical joints is unsupported by a vehicle body. Hence, a dynamic damper is formed. The resonant frequency of the dynamic damper, i.e. a frequency at which vibrations are absorbed can be adjusted by altering the modulus of elasticity and weight of the dynamic damper. Therefore, the necessary vibration damping performance can be obtained despite layout restrictions.
