Race-proven materials are used to create this track-oriented full titanium exhaust system, providing a weight saving of 3,6% (-0,4 kg) over the standard stock version. Two 200 cpsi sport catalytic converters replace two petrol particulate filters for more direct gas flow and two valves – with housing cast in the in-house foundry – have been tailored to provide a deep, resonant rumble at start-up and a racing tone as the revs of the 120° V6 engine rise. The tailpipes are 3D printed for geometrical optimization for performance and visual effect, with the outer sleeve finished with hand-laid carbon fibre, designed to be bumper mounted, with a strikingly different appearance from the standard stock version. Tests conducted by Akrapovič engineers in comparison with vehicles with a standard stock exhaust and an Akrapovič Slip-On Race Line (Titanium) exhaust produced lower back pressure from the Akrapovič Slip-On Race Line (Titanium), offering a performance upgrade potential with mandatory ECU remapping. This lightweight exhaust has been developed for use on closed-course competition circuits only, and it is insulated to prevent heat transfer to the engine compartment.THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
