DescriptionThe whole story▼

The Arrow Thunder 71701PK brings genuine race-bred credentials to the Yamaha YZF-R6 RJ11, pairing a road-legal DB killer with a full titanium canister that strips 1.83 kg from the tail end of your 600. Engineered to Arrow's exacting standards, this slip-on silencer meets noise regulations straight out of the box while delivering the sharper throttle response and free-revving character the R6 platform demands.

Key Features

  • Titanium silencer body resists extreme heat while saving significant weight over the stock unit — 1.83 kg total — for measurably crisper throttle pickup
  • Carbon end cap combines a premium race aesthetic with genuine lightness and thermal durability
  • Stainless steel internal components ensure long service life and consistent flow characteristics, ride after ride
  • DB killer included for full road legality without compromising mid-range performance when removed for track days
  • 270 mm canister length and 50 mm outlet / 54 mm inlet diameters are optimised for the YZF-R6 RJ11 exhaust architecture
  • Arrow recommends pairing with a dedicated ECU mapping for the best throttle response and power delivery across the rev range

Design and Build Quality

Arrow's Thunder range occupies a precise position in the Italian brand's line-up: full race construction materials at a price point accessible to serious road and track riders alike. The 71701PK uses a hand-formed titanium canister — the same grade trusted in Arrow's homologated race systems — finished with a carbon fibre end cap that adds visual aggression without adding grams. Internal baffling is fabricated in stainless steel, giving the Thunder a service life that outlasts conventional mild-steel systems many times over. The result is a silencer that looks at home on a circuit pit lane yet complies with road noise legislation when the DB killer is fitted.

Performance and Mapping

Replacing the heavy factory can with a 1.83 kg titanium unit shifts the centre of mass inward and reduces unsprung rotational inertia at the rear, contributing to more neutral cornering behaviour as well as the obvious straight-line gains from reduced backpressure. To unlock the full performance potential of the Thunder, Arrow and Inter-Pace both recommend the use of a purpose-mapped ECU calibration for the YZF-R6 RJ11. The mapping compensates for the changed exhaust scavenging characteristics and delivers crisp, linear fuelling across the entire rev range, from commuter-friendly low-speed rideability right through to the R6's screaming top end.

Fitment and Compatibility
