YAMAHA YZF-R9 2025-2026 - Akrapovic Exhausts System - S-Y9R17-HAPT
£1,799.00
Model Compatibility
- Yamaha YZF-R9 (2025–2026)
- Yamaha YZF-R9 ABS (2025–2026)
Note on Platform Cross-Compatibility: Unlike older cross-compatible units, this exhaust has a custom high-swept routing designed strictly to mirror the World Supersport Championship styling and fit inside the tight dimensions of the factory YZF-R9 bodywork. It will not fit other Yamaha 890cc naked or touring platforms like the MT-09, XSR900, or Tracer 9 without impacting your clearance or fairing integration.
Key Performance Specifications
- Road Legality: Fully Euro 5+ road-legal with comprehensive EC/ECE type-approval. A high-efficiency catalytic converter is integrated natively inside the unit to maintain road legality.
- Materials: High-grade titanium muffler outer sleeve and end cap mated to optimized stainless steel link pipes, headers, and an underbelly pre-muffler chamber.
- Performance Gain: Delivers an extra 3.0 hp (2.2 kW) at 10,000 rpm and 2.6 Nm of torque at 9,500 rpm.
- Weight Savings: Considerably lighter than the bulky 7.0 kg original exhaust assembly.
- Sound Profile: Emits a distinct, throaty triple-cylinder racing bark while complying safely with legal decibel caps.
Critical Fitment & Mapping Realities
- No ECU Remap Required: Because this is a road-legal system utilizing calibrated backpressure thresholds, it operates perfectly as a plug-and-play installation. The factory fuelling profiles run smoothly with no mandatory ECU remapping required to keep the dashboard clear of error codes.
- Visual Integration: The main pre-muffler container is intentionally hidden low inside the body panels, leaving only the right-side Supersport exit visible to protect the clean silhouette of the R9 fairings.
