CX Carby Plus CX Carby B.o.s. is the most advanced development of the carbon fiber silencer with oval section and it embodies Arrow long term experience in the world of competitive racing. The maxi oval section maintains the overall dimension of the silencer at an optimal size while reducing considerably the sound emission without affecting negatively the performance of the CX Carby exhaust range. CX Carby B.o.s. silencers are manufactured using the craftsmanship procedure typical of ARROW production style, using only the best quality stainless steel and 100 % carbon fiber silencer shell. In order to achieve the highest quality and top performance levels, matching of the exhaust components are individually checked to assure a uniform gas flow. Assembly procedure is done on welding jigs using manual T.I.G. and M.I.G welding process in combination with solid billet aluminium bushings to the cylinder ports. CX Carby B.o.s are available both for stock collectors and as a complete system with high or low intermediate joint. Replacing the silencer allows a considerable weight saving and a consistent performance gain; features that are enhanced even further if the silencer is fitted in combination with the Arrow exhaust collectors.
