Good morning Ferrarichat! I bought my first Ferrari last week and have been getting to know my way around my new car. The previous owner had Maranello in Colorado put in a new Tubi exhaust system with headers etc. and I love the sound, however, leaving for work at 6am I'm sure my neighbors do not. Does anyone know if you can retrofit the valve control system to give you the control over when it screams and when it purrs? I would be very grateful if anyone has done this or can point my in the right direction here.
