    Looking from advice from those that know better than me...

    Have a 2015 California T...
    On my old Cali n/a I unplugged the vacuum tubes to keep the exhaust valves open, and improve the sound.

    I know that I can do that with the Cali T... but being a turbo is there any downside? wondering if backpressure changes etc would affect anything negatively?

    Will be getting this done tomorrow, so grateful for any advice, before I have it done...
    Thanks all...!

    Thanks - yes will be sure to plug with a screw - thanks.
    Any known downside of doing this mod - other than upsetting the neighbours???
