The Evolution Line (Titanium) exhaust system for the Mercedes G 500 is Akrapovič’s first venture into the high-performance off-road market. It is constructed with high-grade durable lightweight titanium to reduce weight. This system is beautifully finished with specially-designed tailpipes exiting on either side of the vehicle, perfectly routed to fit within limited space. It delivers a unique sound for a sporty edge, specially programmed by the Akrapovič Sound Engineers, with a pair of exhaust valves behind the rear mufflers to provide optimal control of the exhaust tones while increasing power and torque levels. This system is ECE type approved.An optional Akrapovič Sound Kit is available to control the different sound settings. Fittment notice: Mandatory fitting kit P-HF1129 is needed for mounting the S-ME/TI/2H evolution system to Mercedes G500 model. ​Optional downpipes do not fit to G500.This system does not fit on vehicles equipped with Otto particulate filter (OPF).
