DescriptionThe whole story▼

Weighing just 1.52 kg, the Arrow Pro-Race slip-on for the Yamaha YZF-R3 pairs genuine all-day rideability with a race-bred soundtrack. The dark stainless steel canister fits seamlessly into the YZF-R3's compact chassis, shedding weight where it counts while keeping the throttle response crisp from the moment you pull away in traffic or head for the open road.

Key Features

  • Lightweight dark stainless steel construction at just 1.52 kg for noticeably sharper throttle response and improved handling balance
  • Road-legal E-number homologation means no compromise on daily usability or MOT compliance
  • Integrated DB-killer included for legal noise levels — remove it when regulations permit for a fuller exhaust note
  • 250 mm canister length tuned for the YZF-R3's power delivery characteristics
  • 68 mm outlet and 45 mm inlet diameters optimised for improved exhaust flow and mid-range pull
  • Stainless steel end cap and internal components throughout for long-term heat resistance and durability

Build Quality and Finish

Arrow's Pro-Race series is built to the same exacting standards as the exhausts found on World Supersport machinery. The dark stainless steel finish gives the canister a purposeful, understated look that suits the YZF-R3's aggressive lines without drawing unwanted attention on a daily commute. Every internal component is manufactured from stainless steel, ensuring the can handles sustained heat cycles without degradation whether you're lane-filtering in the city or pushing hard on a weekend run.

Road and Track Performance

The Pro-Race canister delivers a genuine improvement in throttle response across the rev range. For riders looking to extract every last percentage of performance, Arrow recommends pairing this slip-on with a dedicated ECU mapping developed specifically for the 71831PRN on the Yamaha YZF-R3 — this ensures fuelling is optimised to match the improved exhaust flow rather than relying on the factory map designed for the stock silencer.

Please note: the primary product image has been digitally composited as Arrow has not yet released an official studio photograph for the Yamaha YZF-R3 application. The physical product is identical in specification and finish to that described here.
