Abstract: A catalytic converter for stand-alone application or for use with a novel silencer. The silencer includes a catalytic converter formed from a central housing of a size to house at least one catalytic converter element, an inlet portion connected to the inlet side of the central housing and an outlet portion connected to the outlet side of the central housing. The silencer is formed from a cylindrical housing which is secured on one end to the catalytic converter and on the opposite end to an exhaust pipe of an internal combustion engine. The cylindrical housing has at least one baffle plate transversely mounted therein. The baffle plate has a plurality of perforated conical members positioned opposite each other on each side of the baffle plate. The perforated conical members redirect the flow of exhaust gas through the silencer.
