Track performance, Italian design.

The Arrow racing header is a component developed for Aprilia RSV4 / TUONO V4 EU 2025 (USA 2026). It replaces the catalytic component, optimizing exhaust gas flow and maximizing performance. For TUONO V4, the dedicated UpMap map will be available soon: please wait for its release before completing the setup.

Important technical note

Since the Arrow header removes both the catalytic converter (and related sensors) and the exhaust valve, using the UpMap device is essential. This prevents error messages related to the lambda sensors and the missing exhaust valve, and it restores the correct AFR (Air Fuel Ratio), ensuring engine reliability and optimal performance in a racing configuration.

Product advantages

• Increased power and torque thanks to catalyst removal and optimized exhaust routing.
• Racing construction, with precision welds and CNC joints to reduce turbulence.
• Aggressive look that enhances the bike’s sporting character.
• Weight saving: removing the catalyst reduces weight by approximately -2.8 kg compared to the original component.
  

Compatible with:

• Arrow or OEM silencers (RSV4 / TUONO V4).
• Stock and aftermarket slip-on mufflers.

Note: Designed for closed course competition only, not approved for street use. Legal in California only for racing vehicles that cannot be used, registered or licensed for use on a highway.
