Every element of its construction — from the titanium header to the carbon end cap — reflects the WSS Replica pedigree: uncompromising weight savings, race-proven heat management and an exhaust note calibrated for the track rather than the commute.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull titanium construction throughout the header and silencer body, delivering exceptional heat resistance alongside a dramatic reduction in unsprung mass.\u003c\/li\u003e\n\u003cli\u003eCarbon end cap adds structural rigidity at the silencer outlet while reinforcing the racing aesthetic that defines the WSS Replica range.\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer allows noise output to be tuned to circuit regulations without tooling — leave it in for controlled sessions, pull it for unrestricted performance.\u003c\/li\u003e\n\u003cli\u003eInlet diameter of 60 mm and outlet of 58 mm are sized to optimise exhaust gas velocity on the high-revving R6 four-cylinder.\u003c\/li\u003e\n\u003cli\u003eOverall silencer length of 350 mm keeps mass centralised and tucked cleanly within the R6's bodywork envelope.\u003c\/li\u003e\n\u003cli\u003eDesigned in line with World SuperSport technical specifications, making it a natural choice for club racers and trackday regulars who demand series-proven hardware.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eThe WSS Replica designation is more than a marketing label — it traces a direct lineage to the Arrow systems developed alongside factory-supported teams competing at the highest level of World SuperSport racing. The raw titanium finish darkens with heat to produce the characteristic blue-gold patina familiar from pitlane inspection, while the hand-finished carbon end cap provides a purposeful contrast that no painted or polished alternative can replicate. This is a system built to be seen on a race stand as much as heard on the back straight.\u003c\/p\u003e\u003ch2\u003ePerformance and Engineering\u003c\/h2\u003e\u003cp\u003eThe all-titanium construction is not merely a weight-saving measure — titanium's lower thermal conductivity compared with stainless steel means exhaust gases retain more energy through the pipe, sustaining scavenging pulses that sharpen throttle response across the mid-range and top-end. The result is a more immediate pick-up out of slow corners and a stronger pull to the rev limiter. Arrow recommends pairing the 71218CKZ with a dedicated ECU remap to unlock the full performance potential of the freer-flowing system; without remapping, some top-end power may remain untapped.\u003c\/p\u003e\u003ch3\u003eRace-Use Declaration\u003c\/h3\u003e\u003cp\u003eThis exhaust system carries race-use homologation only.
