The system delivers increased power and torque, reduced overall weight, and a distinctive Akrapovic sound signature, characterized by a deep tone at lower engine speeds and pronounced popping sounds during throttle lift at higher revs. This cat-back exhaust system is manufactured from lightweight titanium and features cast collectors and three mufflers. The central muffler incorporates an internal X-piece to improve exhaust flow, increase power output, and refine acoustic characteristics. Exhaust valves are fully integrated with the factory RS electronics, ensuring seamless operation in all driving modes. Carbon-fibre tailpipes highlight the premium finish and motorsport-inspired design of the system.
