Since 1972 Giannelli Silencers dedicates its effort to design, development and production of exhaust systems for on- and off-road motorcycles. Adding technical competence and innovative spirit to their experience in active motor racing, founders Giorgio and Furio Giannelli created a solid and innovative company. A mix of absolutely reliable materials and qualified resources, plus a intelligent marketing strategy and state-of-the-art technology, enabled Giannelli to reach the highest quality levels and the trademark Giannelli Silencers to be positioned among the top brands in the international market for after market motorcycle products. To reach its excellent commercial and sportive results, Arrow focuses on an intense technical research program supported by international teams and riders. Technical collaboration with top riders such as Max Biaggi, Loris Capirossi, Valentino Rossi, and Marco Melandri, and the high quality and technological standards - fruit of continuous investments in research and product development – guarantee the durability and the high performance of Giannelli products. Giannelli Silencers couples traditional hand crafting to high tech production procedures. Every part of every system leaving the Giannelli plant is extensively tested to guarantee quality, durability and performance. The complete cycle from design to production right up to the distribution of the Giannelli products is carried out at the Giannelli headquarters, situated in the heart of Italy, and covering an area of 20.000 m². In fact, Giannelli systems are 100% Italian made – something that we’re very proud of. Nowadays, Giannelli has the widest range of high-performance exhausts from scooters to street bikes, and a full range of EU Road Approved models, but the latest novelty from Giannelli R&D is the introduction of the IPERSPORT exhaust, adding to the “traditional” superbike exhausts MAXI HOMOLOGATED TITANIUM, CARBON FIBER and ALUMINIUM. The excellent series of EU homologated IPERSPORT exhaust systems is characterized by its typical asymmetrical shape, designed by Giannelli R&D and our Styling department. IPERSPORT is an perfect synthesis between performance and style. The compact silencer has reduced dimensions but elevated silencing power and exalts the aerodynamic line of the motorcycle. Special attention is given to the finishing of the products: all IPERSPORT welding is done and controlled manually. Apart from a titanium, aluminium and carbon version, the silencer is available in stainless steel as well. The new, racy end-cap features an extractable baffle - we call it a dB-killer. Taking out the baffle will greatly increase performance, but of course without it, the system is for closed circuit use only. The IPERSPORT is available as a full system (with exclusive Giannelli headers) or as a slip-on. Giannelli Silencers exports its products in over 40 countries all over the world and participates in all major expo’s in Europe and the USA.
