I'm no TiC, but my guess would be oil wicking for uppipes (oil saturated exhaust wrap doesn't like to be put out if it lights up). Getting more technical, they might discuss the phase change in the material resulting in heating it up to 1200°F+ temperatures and significantly increasing the amount of time it takes to cool down. The resulting state of the material may be more susceptible to cracking due to engine vibration.
