Key Performance Specifications
- Road Legality: Fully EC/ECE type-approved and road legal, but ONLY when paired with the optional plug-in catalytic converter insert. Without the catalyst, it functions strictly as a non-homologated track system.
- Materials: High-grade, premium titanium muffler outer body sleeve paired with a durable high-temperature carbon-fibre bracket, mated to premium stainless steel header loops.
- Performance Maximisation: Delivers an extra 0.6 hp (0.4 kW) at 9,200 rpm and 1.2 Nm of torque at 3,350 rpm. It is carefully tuned to broaden the engine's mid-range power delivery when the VVA cam switches over.
- Weight Reduction: Significantly lighter than the restrictive, single-piece factory original assembly, providing a noticeable weight drop to improve agile handling.
- Tuning Requirements: True plug-and-play installation. Backpressure values coordinate cleanly with the original factory engine parameters, meaning no ECU remapping or re-flashing is required to safeguard the engine or avoid error codes on your dashboard.
