RS2/ES2 intake & exhaust source/fabrication

I'm looking for information on sourcing or fabricating the intake portion for Engine
installed in '90 Coupe Quattro.  The engine is using RS2 turbo, RS2 intake Manifold and
IA exhaust manifold.  The Stock RS2 intercooler with integrated pipe in core support is
being used.

Probably I will need to fabricate the intake pipes, but can likely use stock 3B or
similar hose from MAF/Airbox - I have seen some nice turbo intake hoses from Neuspeed,
etc, so looking for tried and true alternative that facilitate 3" clearance from front
of turbo to core support vertical. 

The turbo outlet to intercooler is 2" and likely can use a 22 deg. + a 45 deg. Section
with overall length of about 12".  There is probably a stock hose that fit the Euro car.

The plumbing going from intercooler out is 2.3" to throttle 3" and could resemble the 3B
layout, but I might route around the firewall over to the passenger side fender well
then around to the intercooler.

Looking for BTDT suggestions, pictures, and flexible DIY tubing  for making convoluted
custom intake plumbing.

Exhaust solution will be addressed later - will likely be using an RS2 dual exhaust
downpipe similar to the 3B setup.
