I think their price point was under $7k for the record. If anything, this manifold will be easier to build (read as cheaper).
As far as the turbo goes, I'm not sure if the precision twin-scroll costs less or more than the V-band; but I can tell you a Garrett twin-scroll is cheaper then a Tial V-band housing. My guess is the twin-scroll design will be cheaper to produce, overall (unless they use a twin gate setup, which may be preferable, but not required).
