Ex-Box series exhaust systems are based on the resonant chamber principle. Inside the Ex-Box, there's a sort of “labyrinth” of successive chambers in which the exhaust gases expands, losing acoustic energy.
The volumes and passages between these chambers are suitably dimensioned and “tuned” based on the pressure waves generated by the engine. In this way, the thermal unit provides excellent yield and good reduction of the decibel level at the exit of the exhaust.

Ex-Box series systems give motorcycles a significant dynamic increase because the exhaust, which is already lighter than the original, is positioned very close to the ground in an area practically free of movement during changes of direction. In addition, since it is positioned below the front wheel axle, it decreases the moment of inertia in braking that depresses the front fork and raises the rear axle.
Ex-Box series exhaust systems give your motorcycle a touch of absolute class thanks to an exclusive design that is unique in the world.
