ABSTRACT:
An exhaust system comprises a catalytic converter placed in flow communication with the exhaust gases from an internal combustion engine and a muffler connected with the catalytic converter. The muffler includes a plurality of exhaust gas conduits arranged to form a continuous exhaust gas flow path via a plurality of expansion chambers, in which at least one of the exhaust conduits, except the first of them, has its exhaust gas inlet end closed and is formed with a group of apertures, or holes, which are disposed and sized, such that broken pieces of catalyst carried by the exhaust gases are prevented from entering the one exhaust gas conduit.
