Nahh. Don’t need a calculator to know stainless has lower thermal conductivity and better high temperature mechanical properties than mild steel. No offense Doug but while what’s better may well be a matter of opinion and tradeoffs, material properties are not.

It’s a fair point. I don’t think TIG is rocket science but agree that it is much more common to find a MIG in a garage. If the welding isn’t an obstacle for you, surprisingly, I found there was little to no net difference in cost between 304 and mild steel construction for the headers I built because by the time I paid for freight both ways and for coating, it was about the same. I spent more on mufflers but that was a choice to buy light repackable mufs.
Best,
