ABSTRACT:
An exhaust system for a vehicle includes a muffler connected to an exhaust pipe, which is in turn connected to an engine. A spark arrester is provided with a tail pipe and connected to the rear end of the muffler, and is capable of discharging an exhaust gas flowing through the muffler through the tail pipe of the spark arrester into the atmosphere. The interior of the muffler can be divided into a plurality of expansion chambers connected by restricting passages by attaching the spark arrester to the muffler to enhance the sound attenuating effect. The interior of the muffler is divided into the plurality of expansion chambers by separators disposed in the muffler and a spark arrester combined with the muffler.
