Competition exhausts have many differences when compared to a standard Arrow exhaust: increased diameters where necessary, different solutions for sections changes and a specially-designed silencer. Each of these features has been designed to ensure a better performance when the exhaust is fitted to a tuned (so more powerful) engine. Competition exhausts represent the top of Arrow product lines: these systems are directly based on the exhausts our technicians in the R&D has developed and keep on developing for the major teams in SBK and SS, throughtout the World, and these masterpieces are made using top materials and top technologies used on tracks. Entirely welded via TIG process, the Competition exhausts are available in 'full titanium' version (totally made using titanium alloy) or with the headers in stainless steel. In both cases the exhausts have a built-in plug to fit an oxygen sensor, so that you can check and change easily and quickly the ECU settings, depending on track and weather conditions. Silencers design give to the bikes the typical Arrow look and also ensures top performances while keeping the noise levels within the requirements stated by racing rules. A version of the silencer is available, with a carbon rear endcap. Moreover, due to the restrictions to noise coming from race activities and due to the checks done on track throughtout Europe, a version of the same silencers is available with a removable dB-killer.
