This is a picture of Chucks Inconel Turbo on his three rotor.

The manifold is also fabricated in Inconel with a less than ideal
location
for the waste gate. It should come out near the center at a 45 degree
angle.
But it appears to work so far.

$300 for a manifold like that is definitely the good-guy deal.  I challenge
you to find anyone who does decent work who would do a one-off similar
manifold for the same price.  I disagree with Paul's comment about
non-ideal wastegate setup.  The fact that it dumps conveniently into the
tailpipe is also important and probably harder to do with symmetrical
setup.  Also moving the turbo out even a little drives up overhang loads
dramatically.  I'm sure there were many other factors (like the huge
actuator housing) that drove Chuck to configure the way he did and compared
to those symmetry would be near the bottom of the list.

I am just going on what the highly experienced Corky Bell said
in his book "Maximum Boost". Get the book and form your own opinion.

Corky says dumping it into the exhaust pipe at less than 18 inches
from the turbine is a no no.
