The success of discharges to tromboncino line Pro-Race and requests them to be mounted even on models particularly demanding from the point of view of noise emissions has given to Arrow find everything to develop a silencer Pro-Race larger than the previous. The design of the silencer Pro-Racing (the final section of the cone diameter increased to 106mm) has allowed us to significantly increase the volume inside the silencer. Furthermore, the extreme flexibility of the components of the cone (different layouts are available, with a single cone or with two sections welded together) allows to design a silencer exhaust perfectly adapted to the design of the motorcycle. Equipped with attacks to the frame welded on the body of the muffler, the silencers of the line Pro-Racing Big are available in stainless steel and welded with TIG. Are available as certified versions and with the choice, for some applications, between the end plate and stainless steel to carbon fiber.
All Arrow silencers approved EU have the inside (dB killer) removed for regeneration and cleaning. The removal of the interior (dB killer) transforms the silencer from approved racing, resulting in better performance, but jeopardizing compliance approval. With discharges approved to EU standards is issued a Certificate of Approval to be attached to the booklet Circulation. After removing the removable cap (dB killer), the EU approved silencers and those racing are exactly identical. For more information, photos and technical specifications (graphic kit with power silencers) consult the website of the Arrow.
NOTES: The silencer mounts directly on the original collectors or the Arrow collectors
