DescriptionThe whole story

Born from World SuperSport competition, the Arrow 71218CKZ is a full titanium exhaust system engineered exclusively for the Yamaha YZF-R6 RJ27. 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.

Key Features

  • Full titanium construction throughout the header and silencer body, delivering exceptional heat resistance alongside a dramatic reduction in unsprung mass.
  • Carbon end cap adds structural rigidity at the silencer outlet while reinforcing the racing aesthetic that defines the WSS Replica range.
  • Removable dB killer allows noise output to be tuned to circuit regulations without tooling — leave it in for controlled sessions, pull it for unrestricted performance.
  • Inlet diameter of 60 mm and outlet of 58 mm are sized to optimise exhaust gas velocity on the high-revving R6 four-cylinder.
  • Overall silencer length of 350 mm keeps mass centralised and tucked cleanly within the R6's bodywork envelope.
  • Designed in line with World SuperSport technical specifications, making it a natural choice for club racers and trackday regulars who demand series-proven hardware.

Design, Finish and Heritage

The 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.

Performance and Engineering

The 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.

Race-Use Declaration

This exhaust system carries race-use homologation only. It does not hold road-legal type approval and must not be fitted to any motorcycle used on public roads. It is intended solely for closed-circuit competition and private trackday use.
