Was looking at that manifold again, I give it just a few hours of run time before it starts coming apart. You gets what you pays for, and IMO you can barely buy the materials to build a good strong turbo manifold out of stainless for $94. One more thing, if they made the header flange out of stainless too, it shouldn't be that easy to drill through, especially at 3/8ths or greater thickness. Most really good turbo manifolds don't use stainless header flanges due to the greater expansion rate of stainless. It tends to shear the studs off the head when it heats up and expands. The bolt holes have to be such a loose fit around the studs that you end up with big time sealing problems. Or, if it's the cheap quality recycled spoons and forks the Chinese use to make their stainless it'll probably just warp and split.
