The Evolution Line (Titanium) for the Mercedes-AMG G 63 has been created with durability in mind as well as performance using high-grade durable lightweight titanium, making the system 45% lighter than the stock system. It is finished with specially-designed tailpipes?? fashioned in the Akrapovic foundry ??exiting on either side of the vehicle, complementing the car?s robust look, perfectly routed to fit within limited space. This system ? with a pair of exhaust valves behind the rear mufflers to provide optimal control of the exhaust tones ? delivers a unique sound that is distinctly deeper and sportier, especially during acceleration and shifting. Power and torque levels are increased through the entire rpm range.Fittment notice: This system does not fit on vehicles equipped with Otto particulate filter (OPF).
