DescriptionThe whole story▼

At just 1.73 kg, the Arrow Thunder Carbon slip-on silencer transforms the daily ride on your Yamaha YZF-R3 into something genuinely rewarding — lighter on the bike, livelier in throttle response, and unmistakably sharper in appearance. Engineered specifically for the YZF-R3 across the 2015–2018 model years, the 71831MK slots straight onto your existing mid-pipe and delivers a ride that feels as good at commuting pace as it does on an open road.

Key Features

  • Weighs just 1.73 kg — a meaningful reduction that sharpens throttle response and reduces unsprung mass for more agile handling.
  • Full carbon construction on the silencer body and end cap delivers premium durability alongside a purposeful, race-inspired finish.
  • Stainless steel internals resist heat and corrosion for consistent, long-term performance across all riding conditions.
  • E-number road approval means the 71831MK is fully street-legal straight out of the box.
  • Integrated db-killer keeps noise within legal limits for everyday use and can be removed on track days.
  • 250 mm silencer length with 45 mm inlet and 45 mm outlet diameters, optimised for the YZF-R3's power character.

Build Quality & Performance

Arrow has used woven carbon fibre for both the main canister and the end cap, giving the Thunder a visual quality that stands apart from painted or wrapped alternatives. The weave is finished to a high standard and holds up to heat cycles without discolouration or delamination. Inside, a stainless steel baffle and internal components ensure that the silencer maintains its performance over time — carbon on the outside, tough where it counts on the inside.

The 45 mm inlet and outlet diameters are sized to work with the YZF-R3's mid-range power delivery, with the 250 mm body length tuned to support a cleaner exhaust pulse. The improvement in throttle feel is noticeable from low revs, making the bike more enjoyable on winding roads as well as in urban traffic where quick, natural responses matter most.

Road Use & Mapping Note

The Thunder 71831MK carries a full E-number homologation, so it can be fitted for everyday road use without paperwork concerns. The removable db-killer makes the transition between road and track straightforward. For riders who want to extract the full potential of the freer-flowing exhaust, Arrow recommends pairing the silencer with a dedicated ECU map calibrated for the YZF-R3 — this optimises fuelling to match the improved exhaust flow and brings out the best in both throttle response and top-end pull.

Please note: the primary product image is a representative render, as Arrow had not yet released a finalised product photograph specifically for the YZF-R3 at the time of listing. The item itself fully matches all specifications described here.
