How to flame color 304SS?

I have a couple nice pieces of 2-1/2" 304SS pipe that I snagged from the scrap bin at Delphi just before I left. I plan to use them for tail pipes for the Corolla. At first I was just going to polish them but I think a nice rainbow finish would look better. Is this something I can do with a MAP or Propane torch?

yes… concentrate teh flame at the tip and it will slowly color towards the other side… be careful with it… i would start with propane and go to map from there…
