Stainless will rust a bit depending on its makeup.
I also read the emmissivity of various materials a couple of days ago , and a polished surface such as stainless is 0.1.
I have an additional stainless barrier between my battery and turbo heat shield covered in bright aluminium tape and a battery blanket around the battery as well. So far so good..
I cannot see why you would want to delete the heat shield as it just sits there looking pretty and maybe if you drive on sand it would slow down sand getting into the wastegate pivot. I used to have constant trouble with a Charade turbo with the wastegate pivot jamming from salty air.
I have modified mine to make it easier to remove and replace by moving the back bolt from the turbo to the bracket where it joins the heat shield, or rather by adding a rivnut to the bracket so that you don't have to have all the stars aligned to do up the bolt on the turbo.
But maybe I am a bit anal.
