Arrow Thunder Titanium Slip-On Silencer Yamaha YZF-R6 RJ11 2006-2007 – 71699PK

Arrow's Thunder series carries a heritage rooted in Italian racing craft, and the titanium finish on this slip-on silencer for the Yamaha YZF-R6 RJ11 is where that lineage shows most clearly. At just 1.63 kg, the 71699PK delivers the unmistakable raw aesthetic of brushed titanium paired with carbon end caps — a combination that looks as purposeful stationary as it does at full tilt on track or road.

Key Features

• Titanium silencer body: exceptional strength-to-weight ratio, natural heat resistance and the distinctive burnished finish Arrow is renowned for.
• Carbon end cap: lightweight, heat-tolerant and visually aggressive — a hallmark of Arrow's race-derived Thunder line.
• Stainless steel internals: corrosion-resistant packing and baffles engineered for longevity and consistent acoustic performance.
• Includes a DB-killer insert for road-legal noise compliance without compromising the exhaust note character.
• 270 mm canister length and a 50 mm outlet / 45 mm inlet diameter optimised for throttle response and mid-to-top-end delivery on the RJ11 inline-four.
• A dedicated Arrow ECU mapping is recommended to fully exploit the weight saving and improved flow — extracting the best throttle response from your R6.

Design, Finish and Heritage

The Thunder titanium finish is not a coating — it is the natural patina of the titanium alloy itself, a material Arrow has worked with since the brand's earliest competition programmes. Each canister develops its own subtle heat-toned character over time, making this silencer genuinely individual to the bike it lives on. The contrast between the raw metallic body and the woven carbon end cap is a studied design choice, nodding directly to Arrow's catalogue of homologated race accessories.

Weighing in at 1.63 kg, the 71699PK is measurably lighter than the OEM silencer it replaces, contributing to a noticeable reduction in unsprung and outboard mass. The result is crisper steering feel and a more alert throttle response — qualities that matter on the YZF-R6's tight, rev-hungry inline-four engine.

Installation Notes

This is a slip-on unit designed to mate with the original Yamaha header. The stock header must remain in place; it is not included and is not replaced by this product. Fitment is a direct swap using the factory mounting points, making installation straightforward. Arrow recommends pairing the silencer with a purpose-built mapping calibrated for the R6 RJ11 to realise the full performance benefit. The DB-killer is supplied fitted and can be removed for closed-circuit use where regulations permit.
