Incredibly lightweight, the exhaust system has been engineered with a power-increasing symmetrical 2-1-2 layout that uses 52mm-57mm diameter tubing with a wall thickness of 0.8mm (0.30in). It is equipped with a catalytic converter and two lambda probes for optimum engine mapping and Euro3 conformity. The system terminates with Ducati's trademark twin under-seat silencers, delivering that unmistakable signature sound of the big bore Desmo 90° L-Twin.
