71822MI Arrow Yamaha R3 2025-2026 steel racing headers

The Arrow racing stainless steel decat header for Yamaha R3 2025-2026 is designed for riders looking to achieve maximum performance, weight reduction, and racing sound from Yamaha’s twin-cylinder supersport motorcycle. Developed using race-derived technology, this racing header removes the stock catalytic converter to improve exhaust gas flow and unleash the true sporty character of the engine.

Constructed from high-quality stainless steel, the Arrow header provides excellent heat resistance, reliability, and durability even under intensive track use. The decat configuration significantly reduces back pressure, improving engine performance especially in the mid and high rpm range.

Thanks to Arrow’s optimized flow design, the system delivers:

Removing the catalytic converter also gives the Yamaha R3 a more direct and aggressive riding character, especially during track and track-day use.

Arrow racing sound for Yamaha R3

The racing header produces a deep, aggressive, and unmistakable exhaust note, enhancing the sporty nature of Yamaha’s twin-cylinder engine and giving the motorcycle a far more racing-oriented tone compared to the OEM setup.

Euro5+ engine warning light issue?

As this is a decat racing header, Euro5+ motorcycles may trigger the MIL / Check Engine light due to the management of the dual lambda sensor system. The recommended solution is the Arrow A.R.D. (Arrow Racing Device), specifically developed to suppress catalyst-removal-related errors without modifying the original ECU mapping.

Why choose the Arrow Racing header?

Because it delivers maximum racing performance for the Yamaha R3, combining reduced weight, aggressive sound, and premium Made in Italy construction quality.
