    I have a 2004 Ferrari 575M with Larini exhausts. Around 4K RPM under moderate to hard throttle I get this "screech" sound. It seems to abate after 5K RPM. It does not happen when bringing up the RPM slowly. The stock vaccum tubes that ran to the OEM exhaust have been capped off. Still, I wonder if the vaccum is not somehow involved. Any ideas would be helpful.

    Thanks
    Mike
