Fabricated my own exhaust manifold for the K03 turbo. After fabrication I sanded and filed the surface flat. Now it warped on me. There's plenty of material to true it again but I was wondering if cutting the flange between the exhaust ports would help in the future.

That used to be standard fix for Mitsubishi Starion factory exhaust manifold that would warp and pull the studs out of the head. I don't see why it would not work for you?

another helpful practice is to saw cut the flange to the stud mounting holes. ;)

Thank you I will do both suggestions prior to surfacing it. At least it's thick enough to do that. The first one I made ended up too thin after surfacing it and I was not looking forward to making a third one.
Thanks again Edd

Got it done. As I was making the first cross cut it bound on the blade and flattened out for the most part when cut. Still trued it a little although it didn't take a lot. Any suggestions or comments on ceramic coating? fiberglass in my hands and arms is getting old. Thanks for you're suggestions
