Built exclusively for track use, the Arrow 71473MI stainless steel header transforms the exhaust flow of the Yamaha YZF-R6 RJ15, sharpening throttle response and unlocking measurable power gains across the rev range. Every dimension is engineered to the precise fitment requirements of the 2012-2016 RJ15 chassis, making it the natural first step in a serious track-day or race-series build.
Key Features
- Purpose-built stainless steel construction delivers outstanding heat resistance and long-term durability under sustained race conditions
- 54 mm outlet diameter optimises exhaust gas velocity for improved mid-range and top-end performance
- Sharper, more immediate throttle response compared to the factory header
- Designed as a direct, precise fit for the Yamaha YZF-R6 RJ15 (2012-2016) — no modification required
- Race-use only homologation keeps weight and restrictions to a minimum for maximum track performance
Build Quality & Performance
Arrow manufactures the 71473MI from high-grade stainless steel, chosen for its exceptional resistance to the thermal cycling that destroys lesser headers over a season of hard use. The tube geometry has been developed specifically around the RJ15 engine's exhaust timing, producing a more linear power delivery and a noticeably crisper throttle feel from the moment you exit a slow corner. At 3.72 kg, the header contributes to a well-balanced overall exhaust system weight without compromising structural integrity.
Track Use & ECU Mapping
The 71473MI carries race-use only approval and is not road-legal. To extract the full performance benefit and ensure long-term reliability, Arrow strongly recommends an ECU remap or custom mapping session following installation. A correctly matched map allows the fuelling and ignition timing to work in concert with the freer-flowing header, preventing lean conditions and maximising the power gains on offer.

This header is designed exclusively for the following model:
