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 Akrapovic dyno against the Mercedes-AMG GLE 63 S Coupe 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 Akrapovic 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 Akrapovic Sound Kit is installed.
