Abstract
A vehicle exhaust device including a rear silencer disposed at the rear portion of a vehicle, a large-capacity silencer having a capacity larger than that of the rear silencer and disposed below a passenger compartment of the vehicle, and an intermediate silencer disposed substantially at the middle of an exhaust tube interconnecting the rear silencer and the large-capacity silencer. With the vehicle exhaust device thus arranged, exhaust noises can be attenuated at a position near an engine forming a noise source, i.e., at the early stage of transmission and with substantially reduced length-dependent resonance of the exhaust tube.
