Interested in pricing myself. Though as far as the second part, and the
nature of turbochargers,  I'd have to venture no. Due to the restriction
of the turbo itself, having a free flowing or tuned exhaust in front of
it will provide zero(measurable) gains whatsoever, at least with any
exhaust system you could fit in the back of a D anyway.. The
backpressure caused by the turbo would  entirely negate any tuning
benefits.  You also have to deal with heat buildup. There's a reason why
most production turbo manifolds are cast iron.. Your gonna have alot
higher temps between the engine and turbo.

I have a few more questions for John too.  What rpm range are these
headers going to be tuned to?  Or are they untuned?  Are they going to
be symmetrical so true dual exhaust can be run, or will they need a
crossover pipe over the transmission similar to the stock system? What's
the OD of the collector output?  Just curious as to what size pipe I'd
end up needing to use to the muffler if I went with these when I got
that far in my rebuild.
