Thanks for the help guys, I will have to keep those cast manifolds in mind. Would be nice to not have to worry about cracking, that is why I am probably going to go with a LIPP cast 02 housing.
Anyways, whatever exhaust mani I go with, it won't be getting wrapped.
Halon, that manifold is set up for an external gate isn't it? I'm set up for internal right now, and dont plan on changing that for the next few summers.
