Arrow's Indy Race line carries decades of Italian racing pedigree, and the 71963PK brings that heritage directly to the Kawasaki ZX-4RR. Crafted from aerospace-grade titanium with a carbon end cap, it pairs exceptional lightness and heat resistance with a finish that looks as purposeful as it performs — whether you're threading through traffic or hunting lap times.

Key Features

  • Titanium canister construction delivers outstanding durability and heat resistance at minimal weight, transforming the rear end aesthetic of the ZX-4RR.
  • Carbon end cap adds a premium, race-derived finishing touch that distinguishes this silencer from stainless-steel alternatives.
  • Removable dB killer included, letting you dial in the sound level for road or track use without buying additional hardware.
  • E-number homologation means the 71963PK is fully road-legal for use on public roads right out of the box.
  • Designed as a direct bolt-on slip-on replacement for ZX-4RR model years 2023 through 2026 — no fabrication required.
  • Compatible with Arrow headers to build a full Arrow exhaust system for maximum performance gains.

Design, Finish and Heritage

The Indy Race name references Arrow's long history supplying silencers to professional racing teams. The natural titanium finish develops its own subtle heat-blued patina over time, giving each unit a genuinely individual character. The woven carbon end cap reinforces the race-bred identity and resists the high temperatures generated by the ZX-4RR's eager inline-four. This is not a cosmetic upgrade bolted to a heavy canister — every material choice here is the same one Arrow's race engineers would make.

Performance on Road and Track

Replacing the restrictive OEM silencer with the 71963PK improves throttle response and liberates power across the rev range of the ZX-4RR's 399 cc engine. For riders who want to push further, pairing this slip-on with a matching Arrow header transforms the installation into a full system, and a custom ECU map is recommended to extract the maximum benefit from the freer-flowing exhaust. On track days the dB killer can be removed in minutes to open up the characteristic Arrow tone; refit it for the road and you retain full E-number compliance.

Fitment and Compatibility

This silencer is engineered specifically for the Kawasaki ZX-4RR across model years 2023, 2024, 2025 and 2026. It is not intended for the standard ZX-4R or earlier ZX-4 variants. Verify your exact model designation before ordering. The unit pairs directly with Arrow headers (sold separately) to form a complete exhaust system.
