{"product_id":"arrow-71221ckz","title":"Arrow Competition Full Exhaust System – Stainless Steel \u0026 Titanium for Yamaha YZF-R3 (2021–2026) 71221CKZ","description":"\u003cp\u003eArrow's Competition full exhaust system for the Yamaha YZF-R3 is the product of decades of racing pedigree distilled into a single, beautifully engineered assembly. Part number 71221CKZ combines a stainless steel header with a titanium slip-on silencer and a carbon end cap — materials chosen not for appearance alone, but because they define the pinnacle of lightweight, heat-resistant exhaust construction. At 3.3 kg complete, this system strips meaningful mass from the R3 and lets the engine breathe the way it was never permitted to from the factory.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull stainless steel header delivers corrosion resistance and precise gas flow geometry developed on the race circuit\u003c\/li\u003e\n\u003cli\u003eTitanium silencer body and internal components reduce rotational and unsprung weight for sharper chassis response\u003c\/li\u003e\n\u003cli\u003eCarbon end cap adds a purposeful race aesthetic and withstands sustained high heat\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer included, giving flexibility between track sessions and noise-regulated venues\u003c\/li\u003e\n\u003cli\u003eDedicated ECU mapping recommended to fully exploit the improved exhaust flow and realise peak power gains\u003c\/li\u003e\n\u003cli\u003eRace-use only design — uncompromising in construction, unrestrained in performance intent\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHeritage, Finish and Build Quality\u003c\/h2\u003e\u003cp\u003eArrow has supplied exhaust systems to championship-winning teams across MotoGP, WorldSBK and the junior classes for more than three decades. The Competition range carries that lineage directly: every weld, every cone and every material choice reflects what Arrow's engineers have learned at the sharp end of motorsport. The contrast between the brushed stainless header, the raw titanium canister and the woven carbon cap is not incidental — it is the visual signature of a system built to the same specification as those leaving the Arrow race workshop in Carpi, Italy.\u003c\/p\u003e\u003ch2\u003ePerformance and Track Use\u003c\/h2\u003e\u003cp\u003eThe YZF-R3 responds well to exhaust upgrades, and the Competition system is designed to extract every available gain from the 321 cc parallel twin. Improved scavenging through the optimised header length and diameter, combined with the free-flowing titanium internals, broadens the usable power band while reducing back-pressure throughout the rev range. Because this system is intended exclusively for track use, there are no road-legal compromises in the tune. For best results, pair the installation with a dedicated fuel map to match the new exhaust characteristics — Arrow recommends remapping as standard practice with the Competition range.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Arrow 71221CKZ is a direct-fit full exhaust system developed specifically for the Yamaha YZF-R3, covering model years 2021 through to 2026.
