Who made these?

[FactBV]

With a cracked original pre-cat manifold, I'm either going to have to take one off and weld it or buy something else. I'm just trying not to spend £1200 on the ACT / JP manifolds, although I bought them before and they were great.

Anyone know who made these http://www.youtube.com/watch?v=6xr1fKvvQ58 ? They look very efficient, with the smaller primaries and blended Y piece.

Dulford used to do a cheaper alternative. Not as shiny but just as effective.
