Giannelli exhausts are built by Furio and Giorgio Giannelli, who in 1972 decided to combine their extensive racing experience with the technology of building race-specification end cans. Today Giannelli leads the way in motorcycle racing across every class. Top riders chase the maximum output from their engines through the Italian company's end cans. The greatest factory riders — Valentino Rossi, Loris Capirossi, Max Biaggi, Andrea Bartolini and many more — have tied their successes to Giannelli. Giannelli's long collaboration with leading factory riders in the world championships has contributed enormously to research and development, both for its racing exhausts and for its road types. The range covers systems for two-stroke and four-stroke sport and on-off models, and equivalents for every scooter on the market. Aluminium, titanium and carbon fibre are used in their construction. The road end cans fully meet EU noise regulations, while production of all exhausts complies with ISO 9001.
