If you want a meaningful upgrade for your Yamaha YZF-R3 without endless complexity, the Arrow Competition full exhaust system 71181CKZ delivers exactly that. At just 2.89 kg for the entire system — header and silencer combined — it sheds real weight over the stock setup while sharpening throttle response in a way you notice from the first lap out. The all-titanium construction keeps things straightforward: light, corrosion-resistant, and built to handle sustained heat without fuss.
Key Features
- Complete titanium header and slip-on silencer combination designed specifically for the Yamaha YZF-R3 (2015-2020)
- Total system weight of just 2.89 kg, reducing unsprung and overall mass for more responsive handling
- Titanium header, titanium silencer body, titanium internals, and carbon end-cap — a purposeful material choice that balances durability with minimal weight
- Removable DB-killer included, letting you dial in noise levels to suit track regulations or personal preference
- 50 mm outlet diameter and 270 mm overall silencer length ensure a clean, direct fitment with no fabrication required
- Improved throttle response and power delivery compared to the OEM system, particularly noticeable in the mid-range
Built for the Track, Practical for the Paddock
The 71181CKZ is a race-use only system — it carries no road homologation — so it is aimed squarely at club racers, trackday regulars, and anyone preparing a dedicated circuit YZF-R3. Arrow's titanium construction is a pragmatic choice here: the material handles the sustained high temperatures of back-to-back sessions without the discolouration or fatigue you would see from stainless, while the carbon end-cap resists impact scuffs that inevitably happen in a busy paddock.
The removable DB-killer is worth highlighting for everyday track use. Many circuits enforce noise limits at scrutineering, and being able to swap the DB-killer in or out in minutes — rather than sourcing a separate insert — saves time and money. When the regulations allow, pull it out and the system breathes freely for maximum performance.
Installation and Mapping
The system is a direct bolt-on for all Yamaha YZF-R3 models from 2015 through 2020, replacing the full OEM exhaust from header to tip. Arrow recommends pairing the system with a dedicated ECU map to fully realise the gains in power delivery and throttle response — without remapping, some of the performance benefit on the upper rev range will remain untapped.
