DescriptionThe whole story▼
Built to the exacting standards of competitive racing, the Arrow Competition full exhaust system 71180CKZ pairs a stainless steel header with a titanium silencer and carbon end cap to deliver a genuinely race-bred exhaust for the Yamaha YZF-R3. Every material choice reflects Arrow's commitment to durability, thermal performance and minimum weight — this is not a road compromise dressed up in race clothing, but a dedicated track system engineered from the ground up.
Key Features
- Stainless steel header provides outstanding heat resistance and long-term structural rigidity under hard track use
- Titanium silencer body keeps mass low while withstanding extreme exhaust temperatures lap after lap
- Carbon end cap adds a further weight saving and delivers an unmistakable race-spec finish
- Titanium internals throughout the silencer section for consistent flow and durability at sustained high revs
- Removable dB killer included, giving flexibility between noise-restricted track days and open competition
- 270 mm silencer length and 50 mm outlet diameter optimised for the YZF-R3's exhaust flow characteristics
Materials and Build Quality
Arrow has built its reputation on selecting the right material for each component rather than applying a single solution across an entire system. Here, the header — the section that bears the greatest thermal shock — is formed from stainless steel, guaranteeing rigidity and corrosion resistance where it matters most. The silencer transitions to titanium, a material that combines exceptional strength-to-weight ratio with natural heat dissipation. The carbon end cap is not merely cosmetic; it reinforces the rear of the silencer while trimming every gram that can be reasonably saved. The result is a system that weighs just 3.49 kg as a complete assembly.
Track Performance
The Competition designation is not marketing language — this system is homologated for race use only and is not road legal. Riders running the Yamaha YZF-R3 in club racing, track days or circuit championships will find that the freer-flowing internals and reduced back-pressure translate directly into throttle response and top-end power. Arrow strongly recommends a dedicated ECU remap or updated fuel mapping to complement the installation and realise the full performance gain the system is capable of delivering.
Fitment and Compatibility
This is a complete exhaust system — header and silencer — designed as a direct-fit replacement for the following:
- Yamaha YZF-R3 (2015, 2016, 2017, 2018, 2019, 2020)
No additional brackets or adaptors are required for the specified fitment years. A full ECU remap is recommended after installation to optimise fuelling for the increased exhaust flow.
