Forza Componenti: http://forzacomponenti.com/
The stock exhaust on the Ferrari F12 sounds incredible, when the exhaust valves are open. The computer by default only opens the valves when the car is under very hard acceleration which means the car doesn’t sound all that great when the valves are closed which is most of the time.
A simple solution to make the car sound loud or quiet when YOU want is to add a Forza Componenti exhaust controller. The controller gives you the option to have the valves open, closed, or default to the computer control. And best of all, it’s very easy to install, and it’s under $400!
