A few shops were mentioned in another thread, and I did searches for them but came up with a link about people who raced house cats around the turn of the previous century, and thoroughbred horse breeders. (Weir Racing)

I did find these guys, though... All flange adapters are about $60. They refer to the CX/DX manifold as an HF, I believe. Does anyone know if this manifold is the same as a HF? Please speak up. I'm pretty sure it is, but there are other people that know Hondas better than I do.
