Arrow Racing Header 71805MI Stainless Steel for Aprilia RSV4 / TUONO V4 EU 2025 (USA 2026)

Track performance, Italian design

The Arrow 71805MI racing header is a component made of AISI 304 stainless steel developed for Aprilia RSV4 / TUONO V4 EU 2025 (USA 2026). It replaces the catalytic component, optimizing exhaust gas flow and maximizing performance.

Designed for track use only, not approved for road traffic.

Important technical note

Since the Arrow 71805MI header removes both the catalytic converter 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 in stainless steel, with precision welds and CNC joints to reduce turbulence.
• Aggressive look that enhances the bike’s sporting character.
• Full compatibility with Arrow silencers or with the original RSV4 / TUONO V4 exhausts.
• Weight saving: removing the catalyst reduces weight by approximately -2.8 kg compared to the original component.
