    I just installed a tubi exhaust with cats on my 1992 F40
    I am now Losing boost from the turbos and I can hear it bleeding off turbo boost, and lost power at high RPM's after I put the Tubi on.

    Peaple are saying it's the lack of back pressure now? Some say that's not the issue at all?

    Any experience out there with Tubi Installs?

    I never have experienced that any aftermarket exhaust works plug and play on the F40. There always need to be some tweeks and adjustments on other things to get it running good again.

    Correct.

    Exactly what type of Tubi unit is this, LM straight-pipes, or the one with the muffler tubes, any images?
