Active Valve Performance Exhaust technology means drivers can for the first time adjust the intensity of the Mustang’s exhaust note to suit their mood and the driving scenario. The innovative Good Neighbour Mode can be programmed to automatically limit the exhaust’s noise output at pre-programmed times of the day to avoid disturbing neighbours, not least when firing up the legendary 5.0-litre V8 early in the morning. #fordmustang #mustanggt #mustangecoboost #mustangshelby #exhaustsound #exhaustsounds Source: Ford
