A high-grade lightweight titanium system finished with hand-crafted carbon-fibre tailpipes and a high-grade austenitic stainless-steel link pipe set.
- Valves on each side calculated to tailor the sound; two acoustic reflectors on the tailpipes guide sound into the cabin

- Two tuned resonators developed for this engine deliver a deep, rich, sporty sound with no drone or streaming, aligned to the straight-six
- Weighs 21.7 kg, 23% lighter than stock
- Power gains of 8.7 kW (11.8 hp) at 5,600 rpm and torque increases of 17.1 Nm at 4,100 rpm, tested on the Akrapovič dyno against a BMW M440i with a standard stock exhaust
- Special parts cast in the in-house foundry
