After adding a full titanium Evolution system, you’ll never want to stop driving. The exhaust system is made of our proprietary titanium and consists of dual-outlet mufflers with exhaust valves, flow-optimized pipes, and a unique cast X-shaped part with resonators. The Evolution lowers the back pressure and gives the M5 more power without removing the catalytic converters. It increases responsiveness and offers a big difference in weight.  Sound is improved too, with a deep sporty sound that grows to an aggressive roar when driven hard but still has no droning. It works well with the M5’s ANC system - just like the valve system, which is regulated through the M5’s settings. Complete the look with a set of four exquisite tailpipes in titanium or carbon fibre.
