Exhaust gas system of an internal combustion engine with integrated pre- and main- silencer

The pre-silencer (4) is arranged as closely as possible to the engine, to one side of the running gear frame (1, 2). The main silencer (5) is arranged on the opposite side of the frame (1, 2). It is fastened to the frame using suitable holders (10, 11). The section of the exhaust pipe (3) which extends between the pre-silencer and the main silencer, crosses under or over the frame.
