Arrow Competition Evo Full Exhaust System Stainless Steel – Yamaha YZF-R6 RJ27 (2017-2026) 71196CKZ

If you want a complete exhaust overhaul for your Yamaha YZF-R6 RJ27 that delivers genuine track performance without the compromises of a bolt-on silencer alone, the Arrow Competition Evo full system 71196CKZ is the straightforward answer. Built specifically for the RJ27 generation (2017–2026), it pairs a stainless steel header with a titanium canister and carbon end cap to cut weight, sharpen throttle response and give the R6's inline-four an exhaust note that matches its character.

Key Features

• Purpose-built fitment for the Yamaha YZF-R6 RJ27 (2017–2026) — no adapter plates or modifications required.
• Stainless steel header construction provides long-term heat resistance and corrosion resistance, making it a sensible choice for riders who use their R6 across multiple track days each season.
• Titanium silencer body keeps unsprung and total system weight to a minimum, contributing to improved handling balance.
• Carbon end cap adds structural rigidity at the tail while giving the system a purposeful, premium finish.
• Titanium internals maximise durability under sustained high-temperature race use.
• Removable dB killer included — run it in place for noise-sensitive circuits or remove it entirely when regulations permit.
• 54 mm inlet / 48 mm outlet dimensions and 350 mm overall silencer length ensure correct gas flow for the R6's engine mapping.

Build Quality and Materials

Arrow has constructed the Competition Evo system around a clear material logic: use stainless steel where corrosion resistance and structural rigidity matter most (the header and collector), and switch to titanium for the canister body and internals where every gram saved translates directly into a livelier chassis feel. The carbon end cap is not decorative trim — it reinforces the outlet section while keeping the assembly light. The result is a cohesive system rather than a collection of parts, and it shows in the quality of the joints and the consistency of the finish.

On Track and Day-to-Day Usability

The Competition Evo is rated for race use only and carries no road homologation. That said, the inclusion of a removable dB killer makes it a genuinely practical choice for club racers and track-day riders who need to pass noise checks at noise-controlled venues. Fit the dB killer for the morning noise test, remove it for qualifying and race sessions. The system is designed to reward a custom ECU map — Arrow recommends a dedicated mapping for optimal throttle response and peak power output, which is standard practice for any full system on a modern fuel-injected motorcycle.

Fitment and Compatibility

This complete exhaust system is designed exclusively for the Yamaha YZF-R6 in the RJ27 chassis variant, covering model years 2017 through 2026. It is not compatible with earlier R6 generations. Always verify your frame and engine codes before ordering.
