Akrapovič exhaust system, manufacturer part number S-ME/TI/15H/1, for Mercedes-AMG GLS 63 (X167) 2020-2023.

This product is made from high-grade  lightweight titanium  for a  weight saving of 34.2%  over the AMG Performance exhaust system. The fully sandblasted exterior is completed with a new tailpipe design constructed from  hand-crafted carbon fibre  with a titanium inner sleeve. Power gains  of 6.3 kW (8.6 hp) and  torque increases  of 21.3 Nm, both at 2,800 rpm, have been achieved when tested on the Akrapovič dyno against the Mercedes-AMG GLE 63 S Coupé with an AMG Performance exhaust system. There are three  exhaust valves , operated by a specially developed control kit: one on either side of the muffler and one in the  active X-connection  in the link pipe to create a perfect sound experience. The housings for the valves, the X-connection, and the reinforcement – or central pillar – of the tailpipes are all cast in the in-house foundry. This produces a pure and  deep distinctive tone , with a full-bodied sound at idle, and a well-defined and strong burble as the revs rise, leading to a high-frequency sound full of sporty character at higher rpms. No remapping is needed on installation. An optional Akrapovič Sound Kit is also available to provide full control over the spectrum of sound emitted from the exhaust. The Evolution Line (Titanium) is ECE type approved for cars with an Otto Particulate Filter (OPF). Designed to fit as a direct replacement to cars which have an AMG Performance exhaust. ECE type approval certificate of the Evolution Line (Titanium) is not valid if the Akrapovič Sound Kit is installed.
