Because of packaging requirements, the EVO system has been split into two codes. Please be aware that both part numbers (MTP-ME/T/5H and E-ME/T/5) must be ordered. The mandatory tail pipe set needs to be ordered separately.Perfectly formed using specially developed ultra-lightweight titanium alloys, this Akrapovič Evolution Line (Titanium) exhaust is designed to replace the performance exhaust fitted to the Mercedes-AMG E 63 and E 63 S. It is finished with hand-crafted carbon-fibre tailpipes in matte or high gloss finish, visually split with a newly designed cast titanium part. This stunning system also includes other parts cast at the in-house foundry, featuring an active X connection and an additional pair of exhaust valves behind the rear mufflers, designed to provide optimal control of the exhaust sound for the best listening enjoyment. The system retains the signature AMG sound, while making it even throatier and richer, and it provides great acoustic feedback both inside and outside the cabin. An increase in performance and torque through a broad rpm range and a significant weight savings of over 45% makes this a very serious performance upgrade. With optimized gas flow and reduced back pressure, it allows limitless tuning options. Because it is ECE type-approved with no need to remap the ECU or add any other parts, it has a simple plug-and-play installation.Fitment notice: The evolution system is designed to replace the AMG Performance Exhaust System.This system does not fit on vehicles equipped with Otto particulate filter (OPF).
