The Evolutionexhaust systemmade of our proprietary titanium consists of newly developed dual-outlet mufflers with exhaust valves, flow-optimized pipes, and a unique cast titanium X-shaped part with resonators. Back pressure is lowered and theM6Gran Coupebenefits from more power throughout the entire range of rpms. It increases responsiveness and an improved power-to-weight ratio has been achieved without removing the catalytic converters. The Evolutionperformance exhaustoffers a deep sporty sound, growing to an aggressive roar when driven hard but without droning. It works well with the M6 Gran Coupes ANC system – just like the valve system, which is regulated through the M6s settings. Complete the look with a set of four exquisite tailpipes intitanium or carbon fibre.
