DescriptionThe whole story▼

The Arrow Indy Race 71963AKN is a road-legal slip-on silencer built specifically for the Kawasaki ZX-4RR, covering model years 2023 through 2026. Constructed from lightweight aluminium with a dark finish and a carbon end cap, it sharpens throttle response and lifts performance on both the daily commute and the occasional track day — all without sacrificing street legality.

Key Features

  • Type-approved with E-number homologation, making it fully legal for road use straight out of the box.
  • Aluminium canister with dark finish delivers excellent heat resistance and long-term durability at a lower weight than steel alternatives.
  • Carbon end cap adds a clean, purposeful visual contrast to the dark body.
  • Supplied with a DB killer for noise compliance, which can be removed for track sessions to unlock the full exhaust note.
  • Direct bolt-on fitment engineered precisely for the ZX-4RR — no modifications required.
  • Compatible with Arrow headers to form a complete exhaust system when an upgrade path is needed later.

Build Quality and Everyday Performance

Arrow's Indy Race line is designed to offer genuine performance gains within the constraints of everyday riding. The aluminium construction keeps unsprung and overall weight low, which is especially noticeable on the ZX-4RR's compact inline-four chassis. The dark anodised finish resists corrosion and road grime, so the silencer keeps looking sharp through seasons of regular use rather than only on track days.

Throttle response across the mid-range improves noticeably compared to the stock unit, giving the ZX-4RR's high-revving four-cylinder a crisper, more connected feel. For riders who want to go further, pairing this slip-on with an Arrow header transforms the setup into a full system. A custom ECU mapping is recommended when making that step to extract the maximum benefit from the combined airflow changes.

Track Capability

With the DB killer removed, the Indy Race opens up to produce the crisp, race-derived exhaust note Arrow is known for. The E-number approval means you can ride to the circuit legally, remove the DB killer in the paddock, and enjoy an unrestricted sound on track — then reverse the process for the ride home. It is a genuinely practical setup for club-level riders who do not want two separate exhausts.

Fitment and Compatibility

This silencer is engineered exclusively for the Kawasaki ZX-4RR across model years 2023, 2024, 2025, and 2026. It mounts directly to the stock mid-pipe using the original mounting points. For a full system build, it is compatible with the corresponding Arrow header for the ZX-4RR. Always verify the part number 71963AKN against your specific model variant before ordering.
