Arrow Stainless Steel Header Yamaha YZF-R6 RJ11 (2006-2007) 71346MI

Engineered exclusively for track use, the Arrow 71346MI stainless steel header delivers a measurable step forward in throttle response and overall power delivery on the Yamaha YZF-R6 RJ11. Constructed from high-grade stainless steel and developed with race-circuit demands in mind, this header is the foundation of a serious performance exhaust build — not a road-going compromise.

Key Features

• Race-use only certification: designed, tested and approved solely for closed-circuit competition, ensuring compliance with track day and racing regulations where road-legal systems are not required.
• High-grade stainless steel construction resists extreme heat cycles and corrosion, maintaining structural integrity race after race.
• 54 mm outlet diameter engineered for optimised exhaust gas flow, supporting improved throttle response and peak power across the rev range.
• Purpose-designed fitment for the Yamaha YZF-R6 RJ11 (2006–2007) — no adaptation or modification required for correct installation.
• ECU remapping recommended to unlock the full performance benefit and ensure long-term reliability after fitment.

Race-Grade Engineering

The Arrow 71346MI header is not a cosmetic upgrade — it is a performance component developed for the rigours of track competition. Stainless steel was chosen for its ability to withstand the sustained heat loads generated by the YZF-R6's inline-four engine at race pace, where temperatures and exhaust gas velocities far exceed those seen in road riding. The 54 mm outlet keeps gas velocity high while allowing the engine to breathe more freely, translating directly into crisper throttle pick-up and a stronger mid-to-top-end pull.

Installation & Setup

Fitting the 71346MI is a direct replacement procedure for the YZF-R6 RJ11's stock header. Arrow and Inter-Pace strongly recommend an ECU remap following installation. Reprogramming the fuelling and ignition maps allows the engine management system to take full advantage of the improved exhaust scavenging, maximising both power output and long-term engine reliability. Running a free-flowing header on the factory map will leave significant performance gains unrealised.

Important Notice

This header is approved for race use only. It does not carry road-use homologation and must not be fitted to any motorcycle operated on public roads. It is intended solely for closed-circuit competition and private track use.
