Video – Akrapovic Auspuffsystem Evolution BMW M5 (F10)

Akrapovic’s Auspuffsystem Evolution exhaust system for the new F10 M5 gives the M5 a power boost of 10hp and 17Nm of torque (12.5 lb-ft), while removing around 12kg (26 pounds) of weight when compared to the standard exhaust. Akrapovic says that the new Evolution exhaust system consists of newly developed dual-outlet mufflers with exhaust valves, flow-optimized pipes, and a unique cast titanium X-shaped part with resonators. The X-pipe, valves, and flange assembly are produced in their foundry. Aside from improving the overall power output, it also gives the M5 more power and torque across the entire range of RPMs. See it in action on this video:
