The Evolution exhaust system made 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 the M6 Gran Coupe benefits 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 Evolution performance exhaust offers a deep sporty sound, growing to an aggressive roar when driven hard but without droning. It works well with the M6 Gran Coupe’s ANC system - just like the valve system, which is regulated through the M6’s settings.Complete the look with a set of four exquisite tailpipes in titanium or carbon fibre.
