Arrow Race-Tech Aluminium Dark Slip-On Silencer Suzuki GSX-R 1000 2017-2023 – 71855AKN

Dropping nearly a kilogram compared to the stock can, the Arrow Race-Tech Aluminium Dark slip-on silencer gives your Suzuki GSX-R 1000 a sharper throttle response and a cleaner soundtrack without compromising its road-legal status. At 2.73 kg and finished in the distinctive dark anodised aluminium with carbon end cap, it is the kind of upgrade that earns its keep on every commute and every track day alike.

Key Features

• Weighs just 2.73 kg — the reduced unsprung and carried mass translates directly into crisper throttle response and improved handling balance.
• Road-legal E-approval number included — fit it and ride without worrying about roadside checks or MOT compliance.
• Integrated dB killer keeps noise within legal limits while preserving the characteristic Arrow exhaust note; removable for closed-circuit use.
• Dark anodised aluminium canister pairs with a carbon end cap for a purposeful, race-influenced appearance that suits the GSX-R's aggressive styling.
• Stainless steel internals and mid-pipe ensure long-term corrosion resistance even in year-round riding conditions.
• Expandable to a full system: pair with an Arrow header to unlock the complete performance package.

Build Quality and Everyday Usability

Arrow engineered the Race-Tech range to bridge the gap between weekend track use and daily road riding. The Aluminium Dark finish is not simply a cosmetic choice — the anodised coating is hard-wearing and resistant to the heat cycles and road grime that quickly age lesser aftermarket cans. The 300 mm canister length and 54 mm inlet / 50 mm outlet dimensions have been selected to optimise mid-range torque delivery precisely where it matters most in real-world traffic conditions.

The stainless steel mid-pipe and internal baffling resist the corrosion that salt and moisture inevitably bring over successive winters, making this an investment that holds its condition season after season. Fitting uses the standard OEM mounting points, so installation is straightforward with basic workshop tools.

Performance and Tuning

Even as a bolt-on slip-on, the 71855AKN delivers a measurable improvement in throttle response throughout the rev range. For riders seeking the maximum return, Arrow recommends using a dedicated ECU mapping developed specifically for this silencer and the GSX-R 1000 engine. That mapping ensures fuel delivery is optimised to complement the improved exhaust flow, extracting the full benefit of the freer-breathing system. Combine the slip-on with an Arrow header and the transformation to a complete performance exhaust is straightforward, with all components designed to work together as an integrated system.
