Arrow Thunder Slip-On Silencer Dark Aluminium – Yamaha YZF-R6 RJ15 (2008-2016) 71699AKN

If you want a genuine upgrade for your Yamaha YZF-R6 RJ15 that works just as well on the daily commute as it does on a spirited weekend blast, the Arrow Thunder 71699AKN hits exactly that mark. At 2.03 kg, the dark-anodised aluminium canister sheds real weight over the stock unit while delivering a deeper, sportier exhaust note — without tipping you into antisocial territory thanks to the included DB-killer.

Key Features

• Lightweight dark aluminium construction at 2.03 kg for improved throttle response and handling balance on the YZF-R6 RJ15
• 270 mm canister length optimised for mid-range delivery and precise power feel at everyday road speeds
• 50 mm outlet and 45 mm inlet diameters promote efficient gas flow while remaining compatible with the original header
• Stainless steel end caps and internal components ensure long-term durability against heat cycling and road use
• DB-killer included for road-legal sound levels straight from the box — remove it for track days if permitted
• Arrow-recommended ECU mapping available separately for best throttle response and peak performance

Build Quality and Everyday Usability

The Thunder canister pairs an anodised dark aluminium outer shell with stainless steel internals and end caps — a combination that handles the sustained heat of stop-start urban riding every bit as well as a hard motorway run. The dark finish resists surface corrosion and sits cleanly alongside the R6's aggressive bodywork without demanding the constant attention a polished surface would. Fitting is a direct slip-on connection to the original stock header, meaning no cutting, no welding and no specialist tools: a straightforward bolt-on that most riders can complete at home in under an hour.

Performance and Sound

The 270 mm canister is tuned to liberate noticeable throttle response across the mid-range where road riding actually happens, rather than chasing a single peak-power headline figure. With the DB-killer in place the note is richer and more characterful than the OEM unit while staying within legal limits for road use. For riders looking to extract the full potential of the system, Arrow's dedicated mapping for the YZF-R6 RJ15 is strongly recommended and available as a separate purchase — it synchronises fuelling to the freer-flowing exhaust and tightens throttle response noticeably.

Important Note

This is a slip-on silencer designed to work with the original Yamaha YZF-R6 RJ15 stock header only. The header is not included. Ensure your standard header is in good condition before fitting. The Arrow Thunder 71699AKN is not compatible with aftermarket full-system headers unless specific fitment has been confirmed.
