Constructed from high-grade titanium, this system aims to enhance the vehicle's performance and deliver a distinctive Akrapovič sound. The deep, resonant tone at lower RPMs transitions to a sportier note at higher revs.\n\nThis Evolution system features three mufflers and utilizes specialized parts cast in Akrapovič's in-house foundry. It incorporates inbuilt valves, seamlessly connected to the RS' standard electronics, allowing for adjustable sound output. The package is completed with striking carbon fibre and titanium tailpipes, emphasizing the car's sporting character. As a cat-back system, it retains the stock catalytic converters, eliminating the need for an ECU remap.
