History Since 1972 Giannelli Silencers has been dedicated to the design, development and production of exhaust systems for on and off road motorcycles. This activity was born from the passion of Furio and Giorgio Giannelli who have combined technical competence and innovative spirit to their experience gained in motorcycles competitions. A careful marketing strategy and the creation of products which are always ahead of their time quickly brought the trademark Giannelli Silencers to the top of the international market with a complete range of silencers and exhausts systems with homologated and non homologated versions for mopeds. Scooters and two and four stroke on and off road motorcycles. Over the years the Giannelli experience has been deepened further by the close collaboration with prestigious motorcycle producers. Giannelli has made available its own technological assets in order to produce systems which are then mounted as first equipment on the models and not as accessories. The complete cycle from design to production right up to the commercialisation of the products is all carried out at the headquarters of Giannelli Silencers, situated in an area of 20.000 m², ISO 9001 certified since 1999. Always keen to follow market needs, Giannelli is the first company in Italy to obtain the national homologation of its products and then, in accordance with the E.E.C directive 97/24 CE, the tough CEE e3 homologation.
