Allen,

I once had a problem with that piece of pipe with the flex coupling.
It was cracked right at the flange where the pipe clamped to the
output of the turbo. You couldn't see the crack and there was no
noticeable exhaust escape at idle speed, but at highway RPM the
pressure would separate the pipe at the crack! The first symptom I
noticed was a noticeable drop in turbo boost pressure. The engine
compartment got so hot that the plastic placard on the Front/Rear
ignition switchover panel started turning up at the corners!
