Arrow Pro-Race Slip-On Silencer Dark Stainless Steel – Yamaha YZF-R3 (2019-2020) 71894PRN

Arrow's Pro-Race lineage is built on decades of racing pedigree, and the 71894PRN brings that heritage straight to the Yamaha YZF-R3. Finished in dark stainless steel with matching stainless end caps, this slip-on silencer pairs an unmistakably purposeful aesthetic with a genuine 1.43 kg kerb weight — a combination that sharpens throttle response and lends the R3 a race-bred character that plain stock exhausts simply cannot match.

Key Features

• Dark stainless steel finish throughout — a subtly aggressive look that sets the YZF-R3 apart from standard trim without resorting to loud visual gimmicks.
• Weighs just 1.43 kg, reducing unsprung mass and contributing to noticeably crisper throttle pick-up and more agile handling.
• Homologated with an E-number for full road-legal use — includes a removable dB killer for street compliance without compromising the Pro-Race soundtrack on track.
• 250 mm canister length and a 68 mm outlet / 45 mm inlet geometry engineered specifically for the YZF-R3's exhaust flow characteristics.
• Inner components, end cap and silencer body all in stainless steel for outstanding corrosion resistance and long service life.
• Arrow recommends pairing with a model-specific ECU mapping to unlock the full performance potential of the Pro-Race system.

Design, Finish and Heritage

The Pro-Race name carries genuine weight in the paddock. Arrow has supplied exhaust systems to World Superbike, MotoGP and Supersport teams for years, and every detail of the Pro-Race range reflects that background. The dark stainless steel treatment gives the 71894PRN a low-key, tactical look — closer to a track-day tool than a chrome showpiece — which suits the YZF-R3's sharp, angular bodywork perfectly. The stainless end cap echoes the canister finish, creating a cohesive appearance whether the silencer is viewed from the kerb or the pit lane.

Performance and Road Use

The slip-on format means fitment is straightforward: the 45 mm inlet connects directly to the existing mid-pipe, and the geometry has been calculated to complement the R3's parallel-twin breathing characteristics. The included dB killer satisfies noise regulations for everyday road use and can be removed for circuit sessions where regulations permit. For riders seeking the most from the system, a dedicated ECU map calibrated to the Pro-Race's flow characteristics will sharpen fuelling across the rev range and extract the full benefit of the reduced back-pressure.
