Key Performance Specifications
- Road Legality: Strictly not street legal. It functions as an un-catalysed full race system without EC/ECE road-use homologation.
- Materials: High-grade stainless steel 2-into-1 header loops mated to a premium carbon-fibre outer muffler sleeve and a matching handmade carbon-fibre end-cap.
- Weight Reduction: Saves an impressive 5.1 kg from the total mass compared to the highly restrictive factory original assembly.
- Performance Maximisation: Drops internal backpressure to unlock an extra 3.3 hp (2.4 kW) and 1.7 Nm of torque at 11,550 rpm on the dyno.
- Sensor Integration: Equipped with dual-threaded bung accommodations supporting both standard M12 and wideband M18 lambda/O2 sensors, facilitating simple data monitoring during tuning.
- Sound Regulation: Delivers a deep, resonant racing grunt. It includes a removable noise-reducing baffle (dB killer part number V-TUV204/1) secured via a single bolt hidden behind a rubber plug.
Critical Euro 5+ (2025–2026) Installation Notes
- Engine Check Light (CEL): When bolting this un-catalysed system onto updated 2025–2026 Euro 5+ models (which rely on dual-channel lambda tracking), the total removal of the catalytic converter will cause the Engine Check Light to appear on your dashboard. An ECU flash or fuel management remap is highly recommended to override the check light parameters and ensure the engine does not run too lean.
- Redesigned Stock Components: For the 2025–2026 generation, Yamaha subtly redesigned the stock bottom body panels and heat shielding. Because this full kit completely eliminates the stock plumbing all the way up to the engine exhaust ports, it clears these changes effortlessly and fits perfectly under the bodywork
