Key Performance Specifications
- Road Legality: Strictly not street legal. It is an un-catalysed competition system engineered exclusively for closed-course racetrack environments.
- Bespoke Titanium Build: Crafted entirely from premium, high-grade titanium alloy across the headers, link sections, internal cores, and outer muffler body sleeve.
- Weight Reduction: Shaves 19.7% (0.8 kg) off the mass of the restrictive factory original assembly, lowering the upper chassis weight to improve agile transitions.
- Performance Maximisation: Drops backpressure completely to unlock an extra 0.7 hp (0.5 kW) at 12,500 rpm and 0.5 Nm of torque at 12,000 rpm on the dyno, flattening out power dips through the mid-to-high rev range.
- Integrated Resonance Chamber: Tailored with a custom loop system and header resonance chamber to directly balance backpressure and satisfy strict FIM trackside competition noise limits.
- Tuning Requirements: True plug-and-play track setup. It runs smoothly out of the box with no mandatory ECU fuel mapping changes required
