stainless steel have greater insulating properities. Mild Steel on the other hand radiates like a champ.
more heat stays inside the stainless tubes and does not get passed into the surrounding air. Mild steel tubes will give off heat rather then insulatling it. It's exactly why SS downpies do better for underhood temps then MS, and why you need to get them thermal coated.
stainless steels conduct less heat but expand more than mild steels.
mild steel is way softer and can manage the expansion and contraction without cracking/tearing. Whereas stainless being harder will tear/crack sooner. I think that's why you don't see any super thick SS manifolds like you see thick mild steel.
