    Does anyone know the part number, or where you can get them?
    I think they use them on the F430?
    Do they come in different sizes?

    Thanks, Dave

    Several Ferraris use a vacuum valve at the end of the exhaust system to increase flow at wide open throttle, but I believe it's after the muffler near the tail pipe tips. I have a complete 360 exhaust out in my garage with the valves on it. I'll take a closer look for a part number later today.
