Arrow Pro-Race Stainless Steel Slip-On Silencer Yamaha YZF-R6 RJ27 (2017-2026) 71863PRI

Riding your Yamaha YZF-R6 day in, day out demands an exhaust that feels at home whether you're threading through traffic or opening up on a favourite B-road. The Arrow Pro-Race slip-on silencer in stainless steel — part number 71863PRI — is road-legal out of the box, sheds meaningful weight over the stock unit at just 1.32 kg, and delivers sharper throttle response every time you crack the grip.

Key Features

• Full stainless steel construction throughout — body, end cap and internals — resists corrosion, handles sustained heat and keeps its finish through year-round use.
• Weighs only 1.32 kg, reducing unsprung and overall mass for noticeably more agile handling on both road and track.
• Type-approved with an E-number, so it fits squarely within road-legal requirements without any additional paperwork or hassle.
• Includes a db-killer insert for compliant noise levels in everyday riding, removable when the situation allows.
• 250 mm canister length with a 45 mm inlet and 68 mm outlet, sized to optimise exhaust flow and mid-range delivery on the RJ27 engine.
• Dedicated Arrow mapping recommended to unlock the full performance benefit and sharpen throttle response to match the freer-flowing exhaust.

Built for the Road, Ready for the Track

Arrow engineered the Pro-Race range to cover both ends of the spectrum — commutable every morning, credible on circuit at the weekend. The all-stainless specification means you won't be nursing corrosion after a wet winter, and the relatively compact 250 mm can sits neatly under the tail without changing the R6's svelte silhouette. The stainless end cap adds a purposeful industrial finish that suits the supersport aesthetic far better than the plastic-heavy OEM unit it replaces.

Throttle response on the YZF-R6 RJ27 is notably crisper once the restrictive stock silencer is removed. The 45 mm inlet flows cleanly into the 68 mm outlet, reducing back-pressure across the rev range and letting the inline-four breathe more freely through the mid and upper registers. Pairing the silencer with the Arrow-recommended ECU mapping brings out the full advantage — improved pick-up from low revs and a more linear power delivery that makes the bike feel more predictable and less fatiguing on long days in the saddle.
