DescriptionThe whole story▼

Built on the same engineering principles used in World SuperSport competition, the Arrow 71217CKZ full exhaust system gives your Yamaha YZF-R6 RJ27 a direct connection to the race paddock. Whether you are preparing for a track day or chasing lap times in anger, this complete stainless and titanium system delivers measurable performance gains and a throttle response that feels immediate and precise — without the compromises of a bolt-on slip-on.

Key Features

  • World SuperSport replica specification designed specifically for the Yamaha YZF-R6 RJ27 (2017-2026)
  • Stainless steel header for exceptional heat resistance and long-term durability under sustained hard use
  • Titanium silencer body keeps weight to an absolute minimum, improving handling balance and acceleration
  • Carbon end cap adds structural rigidity and a purposeful race aesthetic
  • Titanium internals maximise thermal management and resist the punishment of repeat track sessions
  • Removable dB killer included — fit it for controlled noise environments, remove it when regulations allow

Performance and Build Quality

Arrow engineered this system as a complete replacement for the entire factory exhaust, from the header to the silencer exit. The stainless steel header section is formed to optimise gas flow across the R6's rev range, feeding into a titanium silencer that measures 350 mm in length with a 60 mm inlet and 58 mm outlet. Every material choice — stainless, titanium, carbon — is motivated by the same priorities that govern professional racing: weight reduction, heat management, and longevity under extreme conditions.

The result is a system that sharpens throttle response noticeably compared to the OEM unit. Riders will feel the difference in mid-range pickup and top-end pull, particularly when the dB killer is removed. Arrow recommend a dedicated ECU remap or fuel controller calibration to extract the full potential of the system and ensure clean fuelling across all running conditions.

Track Day Flexibility

The integrated removable dB killer makes the 71217CKZ genuinely practical for the track day rider. Many circuits enforce sound limits, and being able to fit the dB killer in minutes means you are not excluded from sessions or forced to borrow unfamiliar equipment. Remove it between sessions when noise restrictions ease and you have a different exhaust note entirely — aggressive, unfiltered, and consistent with a machine prepared for outright performance.
