An exhaust outlet is disclosed, characterized by the presence of an intermediate expansion chamber (4) situated between a collector tube (3) and an outlet tube (5). The intermediate expansion chamber (4) comprises a first portion (6) with divergent walls and a second portion (7) with convergent walls. A discharge orifice (9) is formed in the central zone (8) of the expansion chamber. The expansion chamber (4) captures the particles brought by the gases and discharges them through the discharge orifice (9).
