Arrow Indy-Race Titanium Slip-On Kit Kawasaki ZX-10R/RR (2021-2026) 71215HK

Arrow's Indy-Race lineage draws directly from World Superbike competition, and the 71215HK slip-on kit for the Kawasaki ZX-10R and ZX-10RR is one of its most focused expressions. Constructed throughout in aerospace-grade titanium — canister, mid-pipe and internal components alike — and finished with a carbon end cap, this kit pairs track-proven heritage with a finish quality rarely seen outside a factory pit garage.

Key Features

• Full titanium construction across the canister, mid-pipe and internal components for exceptional heat resistance, corrosion immunity and long-term durability.
• Carbon end cap delivers a purposeful, motorsport-derived aesthetic while shaving additional grams from the tail of the bike.
• Weighs just 2.11 kg — a significant reduction over the stock unit that improves both handling balance and overall performance.
• Includes a DB-killer insert, giving you flexible sound control depending on circuit regulations or testing requirements.
• Designed to pair with an Arrow header and link pipe, allowing straightforward expansion into a full Arrow system at a later stage.
• Race-Use Only homologation — built without restriction for maximum track performance.

Design, Finish and Heritage

The Indy-Race name is no marketing invention. Arrow has supplied exhaust systems at the highest levels of road racing for decades, and the visual language of the 71215HK reflects that pedigree. The raw titanium canister develops a characteristic heat-tempered patina over time — a mark of genuine materials rather than cosmetic coating — while the carbon fibre end cap provides a sharp, contrasting finish that sits perfectly against the ZX-10R's aggressive bodywork.

Every weld, every seam and every joint on this slip-on is executed to the standard Arrow maintains for its competition customers. The result is a component that looks as resolved as it performs, whether the bike is being scrutineered in the paddock or displayed in a well-kept garage.

Performance and Engineering

The all-titanium build is not simply a weight-saving exercise. Titanium's superior thermal properties allow exhaust gases to flow more efficiently than through a steel equivalent, contributing to the improved throttle response and measurable power gains this kit delivers. At 2.11 kg the weight reduction is substantial, and the effect on the ZX-10R's front-to-rear balance is immediately perceptible on corner entry and mid-corner transitions.

The inlet diameter of 76 mm and outlet diameter of 58 mm have been engineered specifically for the ZX-10R/RR's exhaust flow characteristics. The 220 mm canister length is optimised for back-pressure management at race rpm, not street-mapping compromises. Arrow recommends a dedicated ECU remap to extract the full benefit of the improved flow characteristics.

Fitment and Compatibility

This slip-on kit is engineered exclusively for the following models:

• Kawasaki ZX-10R — model years 2021, 2022, 2023, 2024, 2025, 2026
• Kawasaki ZX-10RR — model years 2021, 2022, 2023, 2024, 2025, 2026

The kit can be used as a standalone slip-on replacement or combined with an Arrow header and link pipe to form a complete Arrow exhaust system. A dedicated ECU remap is strongly recommended for optimal power delivery and throttle response.
