Pfab manifold ? Has anyone seen one this bad ? Any suggestions on where to go from here. ?

You can try to contact them and see if they will warranted the manifold and hopefully replace it. But if they try to just reweld it from my experience it won’t last long before it cracks again.

 

First, I agree that even if you reweld it, it'll crack again in short order Secondly, I question if that's a true PFab manifold. I've never seen a PFab in real life, but at least all of the pictures I've seen of them are of higher craftsmanship. Better welds, and fewer welds. They typically have longer curved segments, not so many short sections sorta pie-cut together in the bends.

 

These sorts of issues are pretty common with tubular manifolds. I don't remember hearing of PTuning, Full Race ProStreet, or SOS cracking, but everything else has at least a couple of members with cracked manifolds.
