Akrapovic has released a feature video showcasing their evolution exhaust system for the F10 M5.
The exhaust manufacturer claims a
+10hp,
+17Nm (12.5 lb-ft) torque gain, and
12kg (26 pounds) weight saving over the factory exhaust.
The system is claimed to lower the back pressure and gives the M5 more power and torque through the whole range of RPMs while increasing responsiveness. Gains are achieved without removing the catalytic converters.
The new Evolution exhaust system consists of newly developed dual-outlet mufflers with exhaust valves, flow-optimized pipes, and a cast titanium X-shaped part with resonators. The X-pipe, valves, and flange assembly are produced in the company's foundry. The system is available with either titanium or the carbon fiber exhaust tips seen in the video.
