They look like Tial 38mm gates which are around $450.
They are definatly not 38mm. The Tial 38mm WG are a 2 bolt setup. These ones in the photo are huge. More like the Tial V44 which have V-band connections.
yep, the manifolds come direct from full race...............
about the wastegates...
the wastages are 44mm wastages loaded up with double springs, (not single springs) You run 2 wastages to have absolute control on a spilt pulse turbo setup (one gate per side of the split pulse. (Because the final collector is fully divided into 2 halves you need to run a gate on each side of the collector to equalize boost pressure on both sides.)
