Pro-race trumpet-shaped silencers got a very good success: the need to fit such a silencer on bikes (and engines) really demanding on power and noise output drove Arrow to design and create the Pro-Racing silencer, a bigger version of Pro-Race one. The bigger rear section (increased to 106mm) made it possible to increase the overall volume of the system, with a general benefit in terms of performance and noise levels.

Design possibilities given by the components used on Pro-Racing silencers make possible to Arrow to adapt the Pro-Racing silencer to bikes for style and design, providing an original, powerful and light exhaust. Pro-Racing silencers are secured to the frame by means of a mount welded on the sleeve and, depending on versions, can fit a stainless steel or carbon endcap.
