DescriptionThe whole story

Built exclusively for the Yamaha YZF-R3 and proven on circuit, the Arrow Competition Evo full exhaust system 71180CKR is a race-spec assembly that meets the demands of serious track riders. Its stainless steel headers and titanium silencer body represent a carefully engineered combination of strength, heat resistance and genuine weight reduction — delivering measurable gains in power and throttle response from the first session.

Key Features

  • Race-use only classification ensures every component is optimised purely for track performance, free from road-use compromise
  • Removable dB killer gives you the flexibility to configure the exhaust note to circuit regulations without the need for additional tools or parts
  • Stainless steel headers provide outstanding corrosion resistance and the structural rigidity needed to withstand sustained high-rpm running
  • Titanium silencer body and internal components keep system weight to just 3.61 kg, reducing unsprung and overall mass for sharper handling
  • Carbon end caps add a premium, race-bred aesthetic while contributing to thermal management around the silencer exit
  • Plug-and-play fitment is engineered specifically for the YZF-R3 — no cutting, no adapters, no fabrication required

Performance & Build Quality

Arrow's Competition Evo line is developed directly from their WorldSBK and Supersport racing programmes. The 71180CKR inherits that pedigree: the stainless steel header is mandrel-bent for unrestricted gas flow, and the titanium canister — measuring 270 mm in length with a 50 mm outlet diameter — is sized to maximise mid-range torque and top-end power on the YZF-R3's parallel-twin engine. The titanium internals resist heat fatigue across full-length track days in a way that aluminium or mild-steel alternatives cannot match.

Arrow recommends pairing this system with a dedicated ECU remap or a compatible fuel module. The Competition Evo is engineered to work in conjunction with revised fuelling; without a remap, gains will still be felt, but a tailored map will unlock the full performance and throttle response the system is capable of delivering.

Race Use & Certification

This is a race-use only exhaust system. It is not homologated for road use and is not supplied with or intended to carry any road-legal certification. It is the rider's and team's responsibility to confirm compliance with the sporting regulations of the relevant circuit or championship before fitting. The removable dB killer assists in meeting circuit noise limits where applicable.
