Weighing just 2.73 kg, the Arrow Race-Tech Aluminium slip-on silencer for the Suzuki GSX-R 1000 (2017-2023) delivers a noticeable reduction in unsprung and overall mass — freeing up throttle response and sharpening the character of one of Suzuki's most celebrated superbikes. Road-legal from the outset, it slips straight into your daily ride without compromise.

Key Features

• E-number road approval included — fully street-legal straight out of the box, with a removable dB killer for sound compliance
• 300 mm silencer length with 54 mm inlet and 50 mm outlet, engineered for precise power delivery across the rev range

Build Quality and Performance

Arrow's Race-Tech line represents the Italian manufacturer's benchmark for road-oriented performance exhausts. The silencer shell is formed from aircraft-grade aluminium, chosen for its ideal balance of rigidity and low mass. The stainless steel mid-pipe and internal baffling resist corrosion and maintain their geometry session after session, whether you are commuting through city traffic or pushing hard on a Sunday morning run. The carbon end cap is not simply a cosmetic flourish — it actively insulates the tail of the can and complements the aluminium body with a purposeful, race-derived look that suits the GSX-R 1000's aggressive styling.

The integrated dB killer keeps the exhaust within legal noise limits for road use. It is designed to be removed cleanly should you wish to run the silencer in a track-day or closed-road environment where regulations permit. Arrow also recommends using a dedicated ECU mapping calibrated for this silencer to maximise throttle response, power output, and long-term reliability — an investment that makes the most of the hardware.
