Arrow Pro-Race Slip-On Silencer Stainless Steel – Kawasaki ZX-10R/RR (2021-2026) 71928PRI

The Arrow Pro-Race 71928PRI is the practical upgrade every ZX-10R and ZX-10RR owner has been waiting for: a road-legal slip-on silencer that shaves meaningful weight, sharpens throttle response and delivers that unmistakable Arrow exhaust note — all without demanding a track-only compromise. At just 1.32 kg, it slots straight onto your existing headers and transforms the daily character of Kawasaki's superbike.

Key Features

• E-approval road certification included as standard, with a DB-Killer for full street-legal compliance — remove it for track days when regulations allow.
• Weighs only 1.32 kg, reducing unsprung and overall mass for noticeably quicker throttle response and more agile handling.
• Stainless steel canister, end cap and internals deliver long-term durability and resistance to corrosion, discolouration and heat cycling.
• Titanium mid-pipe keeps overall system weight low while handling the extreme temperatures generated by the ZX-10R's inline-four.
• Canister length of 200 mm and a 68 mm outlet / 60 mm inlet diameter are optimised for this specific fitment — not a one-size adaptation.
• Compatible with Arrow headers to form a complete exhaust system, giving you a clear upgrade path when you want even more performance.

Built for the Road, Ready for the Track

Arrow's Pro-Race range sits at the meeting point of everyday usability and genuine performance engineering. The stainless steel body resists the knocks and vibrations of daily commuting as confidently as it handles a full track-day session at Brands Hatch or the Nürburgring. The included DB-Killer keeps the system within legal noise limits for road registration, while its straightforward removal transforms the exhaust note for circuit use. Unlike some race-only systems that require remapping before they will run cleanly, the 71928PRI is a well-sorted road upgrade from the first ride — though Arrow recommends a dedicated mapping calibration to extract the full performance benefit, particularly if you are combining it with other engine modifications.

Materials and Construction

Arrow constructs this silencer around a stainless steel core throughout: the outer canister, the end cap, and the internal components are all stainless, meaning heat management and structural integrity are consistent across the entire unit. The titanium mid-pipe adds lightness where it matters most, reducing the lever-arm effect on the mounting points and keeping total system weight remarkably low. The result is a silencer that looks purposeful and industrial without resorting to carbon-fibre finishes that can look out of place on a road-registered machine used through winter months.

Fitment and Compatibility

This silencer is designed as a direct-fit replacement for the Kawasaki ZX-10R and ZX-10RR covering model years 2021 through to 2026. No modification to the original mounting points is required for a standard slip-on installation. It can be paired with Arrow's own header system to create a full Arrow exhaust package for greater performance gains. Arrow recommends a dedicated ECU mapping file when fitting this exhaust, especially in combination with an Arrow header or other engine modifications.
