DescriptionThe whole story▼
If you want a genuine upgrade over the stock exhaust on your Suzuki GSX-R 1000 without sacrificing road legality or long-term reliability, the Arrow X-Kone 71855XKI is the most sensible starting point. Road-approved with an E-number, built entirely from stainless steel and weighing just 2.03 kg, it delivers a cleaner throttle response and a more purposeful exhaust note on every commute or weekend ride — not just on track days.
Key Features
- Full stainless steel construction throughout — canister, end cap and internals — for outstanding corrosion resistance and service life under all weather conditions.
- Weighs only 2.03 kg, reducing unsprung mass and sharpening throttle response compared to the heavier OEM silencer.
- E-number road approval included as standard, so the silencer is legal for everyday street use straight out of the box.
- Integrated db killer keeps sound levels within legal limits for road riding and can be removed for track sessions where regulations permit.
- 50 mm outlet and 54 mm inlet diameters are optimised for the GSX-R 1000's exhaust flow characteristics, supporting consistent mid-range delivery.
- Can be combined with an Arrow header to create a full exhaust system — a cost-effective upgrade path if your build evolves over time.
Build Quality and Everyday Usability
The X-Kone takes its name from the distinctive conical silencer profile Arrow uses across its stainless range. Unlike titanium or carbon alternatives that demand careful cleaning regimes, the all-stainless build of the 71855XKI shrugs off road salt, rain and heat cycles without discolouring or corroding. The stainless end cap carries the same durability through to the outlet, so the silencer looks as purposeful after two winters as it did on day one.
At 300 mm in length the canister sits neatly within the original GSX-R 1000 bodywork envelope, avoiding the fitment compromises that can arise with oversized aftermarket cans. Installation follows Arrow's standard slip-on procedure using the factory connection point, keeping the process straightforward for a home mechanic with basic tools.
Performance and Mapping
The weight saving over the stock unit translates directly into a more agile feel, particularly when changing direction on a flowing road. Arrow recommends pairing the 71855XKI with a dedicated ECU map tuned to the modified exhaust parameters. A proper map optimises fuelling across the rev range, improves throttle response at part-load and maximises the durability of the system over time. While the silencer will bolt on and run without a remap, a custom or Arrow-recommended map is the logical companion to get the most from the installation.
Fitment and Compatibility
This silencer is designed specifically for the Suzuki GSX-R 1000 covering model years 2017 through to 2023. It connects directly to the standard header on these machines. For riders who already run or plan to fit an Arrow header, the X-Kone slip-on integrates seamlessly to form a complete Arrow exhaust system.
