Exhaust Collectors SXV 450/550 Arrow

Line Off-Road MX Competition is the culmination of the development work that Arrow has done in past years with the top teams of the World Cross. Years of victories and satisfactions, we all remember the strip of world titles won since 1999. Discharges Off-Road MX Competition are designed to transfer the technology developed for racing cross in a series product: innovative layout, components obtained through machining with CNC machines, advanced materials, assembly processes and welding of the highest level. Discharges Off-Road MX Competition are composed of three parts: collector, link Pipe and silencer. The junction areas between the components involve the use of parts CNC machined from billet, to ensure sealing, perfect coupling due to better control of tolerances, reliability and durability. The decomposition of the discharge in three components ensures easy mounting, greater structural strength, a better absorption of the stresses and vibrations transmitted from the frame at the exhaust. In addition, since an inconvenience can happen, makes it easier to replace the part of the exhaust that maybe has dented for a fall, without having to replace the entire system. Collector and connectors are made of titanium: diameters, section variations and passages are carefully designed to bring out the best from the engine, while reducing size and weight. The collector is fixed to the cylinder by a bushing machined (obtained by means of numerical control machining, designed to minimize any interference to the flow of exhaust gas) and a flange made of aluminum alloy. Even the coupling with the connection is secured by a bushing machined. The link Pipe is secured to the frame by means of an attack, which increases the rigidity and stability of the entire exhaust system. The silencer, full titanium, ensures reduced dimensions to a minimum: the profile of the front and rear ride is specifically designed to reduce the total length of the muffler, making the most of the internal volume and available space on the bike. Sound-absorbing materials are of the latest generation, developed specifically for Arrow to meet the increasingly stringent noise limits imposed by the regulations of the race.

NOTES: collectors fit only with Arrow silencer
