Does Andris still modify manifolds that you know of? I saw the manifold ChrisCar was selling and he mentioned that Andris works for Mazda Racing now (I got the feeling that he doesn't do it anymore). I wanted to see what direction you were going. I've been in contact with JM Fabrications and they have done this to man DSM manifolds, so I will probably go with them since they are local.
I don't know about Vegas Sushi!
