ABSTRACT:
An exhaust outlet with venturi is disclosed, comprising an upstream portion (18) in the form of a venturi, defined by upstream walls (16) converging at an open angle and connected, in a narrowed portion (15) to downstream walls (17) diverging at a more reduced angle and a cylindrical downstream portion (3) connected continuously to the downstream walls (17) of the upstream portion (18). The presence of the upstream portion in the form of a venturi substantially reduces the backlash noise without substantially affecting the available power of the engine.
