Silencer Exhaust Arrow RS4 125 X-Kone Approved (from 2017)

Arrow X-Kone exhausts silencers 71844XKI are originally developed to be used in "Competition” and "Competition Full Titanium” full systems for track use, these silencers are now available for a range of naked and sportbike. X-Kone silencers are street legal with removable baffle, with internal components in stainless steel, noise reduction by absorbtion (to reduce the weight of internal structure). Silencer body is made in NiChrom (stainless steel alloy) with a satin finish. Depending on applications, X-Kone silencers can be fitted to original pipes or to Arrow collectors kits by means of a stainless steel mid-pipe and the silencers are secured to the footrest by means of a mount, welded on silencer body. Weight of an X-kone silencer is around 2.2kg (a 30/40% reduction with respect to original silencer) and depending on the level of the system (as a slip on on original pipes or as a full system with Arrow collcectors kit) power and torque output is noticeably better.

Arrow EU approved exhausts have rear cap removable (Db-killer) and are supplied with certificate of approval to be attached to the vehicle registration certificate. Removal of Db-killer transforms the silencer from homologated to racing, generating a performance improvement, but lost the approval compliance. The assembly does not require changes to the carburation, mappings or the use of additional units.

NOTES: silencer fit only with Arrow link pipe 51014 for original collector (sold separately)
