£2,037.00
Model Compatibility
- Yamaha YZF-R7 (2026)
- Yamaha YZF-R7 ABS (2026)
Key Performance Specifications
- Road Legality: Strictly not street legal. It is a non-homologated, track-only system supplied without a catalytic converter.
- Full Titanium Build: Unlike standard racing systems that use stainless steel header pipes, the entire system—including headers, link pipes, muffler outer sleeve, and end-cap—is crafted entirely from high-grade titanium alloy.
- Weight Reduction: Saves an extreme 3.0 kg to 3.1 kg compared to the heavy factory setup.
- Performance Maximisation: Bypasses restriction to deliver an additional 5.9 hp (4.3 kW) at 9,700 rpm and 2.9 Nm of torque at 5,500 rpm.
- Sound Regulation: The system includes a removable noise insert (dB killer). With the insert installed, static noise measures 92.8 dB at 5,000 rpm; removing it creates an aggressive 96.8 dB racetrack bark.
Critical Installation & Electronics Realities
- Mandatory ECU Remapping: Because this unrestricted system maximizes airflow and deletes backpressure, Akrapovič notes that a custom ECU flash or fuel tuner map is mandatory. Running it on a stock fuel profile will cause the engine to run dangerously lean and degrade engine durability.
- Euro 5+ Lambda Sensor CEL: The 2026 YZF-R7 uses dual O2 sensors tracking Euro 5+ parameters. Installing this un-catalysed system will trigger an Engine Check Light (CEL) because the computer identifies a major deviation from stock parameters. Your custom ECU tune must disable or bypass this reading to keep the dash clear.
- Optional Hanger Customisation: Designed to fit seamlessly behind the stock lower fairings, leaving only a slash-cut tip visible on the right. If you are prepping for track days and want to drop the passenger footpegs, it links perfectly with the optional Akrapovič Aluminium Muffler Bracket (Part Number: P-MBY7R5).
