I put this information out almost 4 years ago. This is why I ceramic coated my downpipes when I was one of the first people in the world to install catless downpipes on the F10 M5. Applying heat wrap is always a good idea too. I even heat wrapped the section 1 on my RPi exhaust, mostly so the heat wouldn't interact with the new oil lines I installed for my upgraded transmission cooling system.
