Abstract
An exhaust system for an internal combustion engine includes an outer housing having a front shell and a rear shell, a prechamber in which exhaust gas from the combustion chamber enters, and an intermediate shell having a front and back as well as a catalytic converter holder. A catalytic converter element is arranged on the catalytic converter holder where an exhaust port directs exhaust gas from the catalytic converter element. To place the center of gravity of the exhaust system near the internal combustion engine or cylinder, the intermediate shell forms the prechamber and the exhaust port.
