Arrow Indy-Race Aluminium Slip-On Silencer Kawasaki ZX-10R/RR (2021-2026) 71928AK

Crafted from aircraft-grade aluminium with a carbon end cap and stainless steel internals, the Arrow Indy-Race slip-on silencer 71928AK is a masterclass in lightweight precision engineering. Developed specifically for the Kawasaki ZX-10R and ZX-10RR (2021–2026), it tips the scales at just 2.12 kg while delivering genuinely improved throttle response and a noticeable power uplift over the heavy OEM unit.

Key Features

• Premium aluminium silencer body keeps weight to just 2.12 kg for improved handling and power-to-weight gains.
• Carbon end cap adds a race-bred aesthetic and further reduces overall mass.
• Stainless steel internal components ensure exceptional heat resistance and long-term durability.
• Titanium mid-pipe delivers consistent performance and outstanding corrosion resistance.
• E-mark road approval included — fully street-legal straight out of the box.
• DB-Killer supplied as standard, giving you full volume control for road and track use.
• Compatible with Arrow headers to build a complete high-performance exhaust system.

Build Quality and Materials

Where many slip-on silencers compromise on internals to hit a price point, the Arrow Indy-Race 71928AK takes a different approach. The outer canister is formed from high-grade aluminium — light, thermally stable, and resistant to the stone strikes and weather that come with real-world riding. Inside, stainless steel baffling and packing retain their integrity across thousands of heat cycles, while the titanium mid-pipe bridges the connection between your stock headers and the new silencer with minimal weight penalty and zero rust risk.

The carbon end cap is not a cosmetic afterthought; it completes the thermal management story and gives the exhaust a visual signature that reads as genuinely performance-oriented rather than factory-fitted.

Performance and Sound

The Indy-Race name has track pedigree, and this silencer earns it. The optimised flow path sharpens throttle response across the mid-range and extends top-end pull on the ZX-10R and ZX-10RR, transforming the character of the engine without requiring an ECU remap as a prerequisite — though Arrow recommends a bespoke mapping to extract maximum performance and the sharpest possible throttle response. The included DB-Killer clips in cleanly when noise limits apply and removes in seconds when they do not.

Road and Track Use

The factory-fitted E-mark certification means the 71928AK satisfies legal requirements for road registration in all E-mark countries without any additional paperwork. For track days where noise regulations are stricter, the DB-Killer drops output to a compliant level. Riders who want to push further can pair this silencer with an Arrow header to create a full Arrow exhaust system, unlocking the complete flow and sound profile the Indy-Race was designed around.
