Proper fab work good sir. I've installed and tested several Swaintech coated parts over the years. The thermal reduction is quite significant and they all lasted besides one very hard-use cast iron exhaust manifold on a 4G63, which did have a small section at the collector where the coating "popped off". According to swaintech there is still coating left on the material when this happens and it doesn't degrade the performance much.
I do however, like to make sure stainless parts have been through a few heat cycles before I send them off just to make sure anything that's going to shift or tweak has already done so. While I haven't taken thermal gun readings, it does appear to be quite a bit more effective in the "accidentally touch the header and not nuke all my skin off" or the "tighten those turbo bolts because somebody forgot and we just did a dyno run" tests vs the stuff full race uses (I think it's cerakote?).
Also, I have a friend who now owns Headershield (
https://headershield.com/), and I've been impressed with that product as well. Obviously not a coating but seems very effective in it's own right. My friends longtube 6-2-1 turbo manifolds on his Z31 are wrapped in it and the engine bay heat is down even compared to when they were wrapped with traditional wrap.
