I was wondering if there is any other twin turbo exhaust manifolds that were made out of steel or anything else other than cast iron?

If so let me know.

I was thinking of asking a exhaust guy that my work uses if he would be able to make a manifold. He has made other manifolds for us and I trust his work. What do you guys think?

If we can get this done this would help out on lowing heat in the engine bay.

 

The problem would be the complexity of the sequential systema nd keeping that functionality. If i knew a welder that could make something that stands up to the heat and retains the stock sequential functionality, i would jump on it.

 

No, there is no other manifold available.

Getting one welded is not practical either, since you'd need to build in the flapper doors too for the sequential control, and there is just so little space.
