DescriptionThe whole story▼

Shaving nearly 2 kg from your YZF-R6's exhaust system, the Arrow Thunder 71699AO is the slip-on of choice for riders who want genuine track-ready weight reduction and sharper throttle response without sacrificing road legality. Machined from aerospace-grade aluminium with stainless steel end caps and internal components, it pairs with your original header to deliver the Thunder's signature aggressive soundtrack and improved power delivery across the rev range.

Key Features

  • Lightweight aluminium canister weighing just 1.93 kg — measurable mass reduction that sharpens acceleration and handling balance on track
  • 270 mm canister length optimised for the RJ15's power characteristics, delivering precise, progressive throttle response
  • 50 mm outlet and 45 mm inlet diameter maximise exhaust flow and mid-to-top-end performance gains
  • Stainless steel end cap and internal components resist corrosion and high-cycle heat fatigue through hard track sessions
  • Includes a removable dB killer for E-marked road compliance — pull it for pit lane and circuits
  • Arrow-developed ECU mapping available to fully unlock performance on the YZF-R6 RJ15

Engineering & Build Quality

The Thunder canister body is constructed from high-grade aluminium chosen for its thermal resistance and structural rigidity at sustained high temperatures. Unlike steel alternatives, the alloy shell dissipates heat efficiently and holds its shape through repeated track cycles. The stainless steel end cap adds a purposeful racing aesthetic while protecting the outlet from stone strikes and exhaust back-pressure fatigue. Internal baffling is also fabricated in stainless steel, ensuring consistent flow characteristics mile after mile.

On Track and On Road

The Arrow Thunder is engineered to perform equally in both environments. With the dB killer installed, the 71699AO carries a full E-number road homologation — you can ride it to the circuit, sign on, remove the insert, and experience the full acoustic and performance character Arrow intended. For the cleanest power curve, Arrow strongly recommends running a purpose-built ECU map alongside this silencer; the stock fuelling will work, but optimised mapping transforms throttle response and pulls additional horsepower through every gear.

Fitment & Compatibility

This slip-on silencer is a direct, bolt-on fitment for the Yamaha YZF-R6 RJ15 covering model years 2008 through to 2016. It connects to the standard factory header — the original header must be retained, as no aftermarket collector is included or required. No additional brackets or adaptor pieces are needed for installation.
