Akrapovic 2017 Porsche Panamera 4/Sport Turismo (971) Slip-On Race Line (Titanium) (Req. Tips).

This stunning system is made completely from high-grade titanium. It includes parts cast in the company’s in-house foundry, featuring an additional pair of exhaust valves behind the rear mufflers, designed to provide optimal control of the exhaust sound for the best aural enjoyment. The system has been perfectly tuned to deliver the very best sound experience in all modes – enormous effort was invested to give it a rich higher-frequency V6 sound with a sporty racing note, while keeping it smooth and eliminating any drone for maximum everyday comfort. By using the optional Akrapovic Sound Kit, the driver can choose between a loud racy sound or a quieter note for long-distance driving, regardless of the mode chosen for the vehicle. The look of the Slip-On system can also be further enhanced by adding four round titanium or carbon-fiber tailpipes.
