At just 3.21 kg complete, it delivers a meaningful reduction in unsprung and total mass, sharpening throttle response and handling in equal measure — making every lap a more connected, rewarding experience.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull titanium construction throughout — header, silencer body and internals — combining extreme lightness with outstanding heat resistance and longevity.\u003c\/li\u003e\n\u003cli\u003eComplete system weight of just 3.21 kg for genuine mass reduction and improved handling on the YZF-R3.\u003c\/li\u003e\n\u003cli\u003eCarbon end caps add structural rigidity and a purposeful racing aesthetic.\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer included — adjust sound output to suit the circuit or noise regulations of the day.\u003c\/li\u003e\n\u003cli\u003eSilencer outlet diameter of 50 mm and overall silencer length of 270 mm, optimised for competition flow characteristics.\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on fitment engineered specifically for the Yamaha YZF-R3 2015–2020 — no modifications required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance and Build Quality\u003c\/h2\u003e\u003cp\u003eThe Competition Evo name is not marketing shorthand — this system is designed exclusively for race use. The titanium header feeds exhaust gases efficiently into a titanium silencer with titanium internals, minimising thermal soak and maximising scavenging effect across the rev range. The result is sharper, cleaner throttle response at race pace, where the standard steel system's weight and flow restrictions become most apparent.\u003c\/p\u003e\u003cp\u003eCarbon end caps complete the package, resisting heat and vibration at sustained high rpm while keeping total system weight to its class-leading minimum. Arrow recommends a dedicated ECU remap or custom mapping to unlock the full performance benefit of this system — fuelling that was calibrated around the stock exhaust will not take full advantage of the improved flow.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis system is designed and manufactured to fit the following motorcycle directly:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eYamaha YZF-R3 — model years 2015, 2016, 2017, 2018, 2019, 2020\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eRace use only.
