Using experience gained when creating the first system for the Panamera Turbo, we made this new system noticeably louder with a deep, aggressive sound that fully expresses the racing oriented nature of this new exhaust. By using the optional Akrapovic sound kit, the driver can choose between a loud racy sound or a quieter note for long-distance driving. The dual-mode performance exhaust system can be used with the factory button. This Evolution system also adds more power and torque, improves power distribution, and also reduces weight.
