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.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTitanium silencer body resists extreme heat while saving significant weight over the stock unit — 1.83 kg total — for measurably crisper throttle pickup\u003c\/li\u003e\n\u003cli\u003eCarbon end cap combines a premium race aesthetic with genuine lightness and thermal durability\u003c\/li\u003e\n\u003cli\u003eStainless steel internal components ensure long service life and consistent flow characteristics, ride after ride\u003c\/li\u003e\n\u003cli\u003eDB killer included for full road legality without compromising mid-range performance when removed for track days\u003c\/li\u003e\n\u003cli\u003e270 mm canister length and 50 mm outlet \/ 54 mm inlet diameters are optimised for the YZF-R6 RJ11 exhaust architecture\u003c\/li\u003e\n\u003cli\u003eArrow recommends pairing with a dedicated ECU mapping for the best throttle response and power delivery across the rev range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign and Build Quality\u003c\/h2\u003e\u003cp\u003eArrow'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.\u003c\/p\u003e\u003ch2\u003ePerformance and Mapping\u003c\/h2\u003e\u003cp\u003eReplacing 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.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Arrow Thunder 71701PK is designed exclusively for the Yamaha YZF-R6 RJ11 covering model years 2006 and 2007.
