Full exhaust system ARROW with RACING NOT HOMOLOGATED MANIFOLD and muffler silencer INDY RACE ALUMINIUM DARK homologated EURO5 for APRILIA TUONO 660 21 -- 24

Indy-Race silencers were designed to be used on certain applications, mainly those requiring an under-seat silencer (making it difficult to use other Arrow’s available sections), but once available Indy-Race silencers were used also in some “standard” systems. Design has been inspired by the shape of certain US racetracks (this is the reason for the name of the range) and the section makes it possible to reduce dimensions whilst keeping a good internal volume to damp the noise with a very good power output. Internal parts are in stainless steel, TIG/MIG welded, the silencer body is available in titanium, carbon fiber and aluminum and a carbon endcap is also available as a choice. Indy-Race silencers are available in a street legal version, with removable baffle.
