What I think is happening is due to a combination of things. The idle mixture is a little rich and you have unburned fuel going through a stainless exhaust, stainless retains heat better than steel, and the exhaust is very short and close to the hot turbo after a drive.
So the super heated, unburned fuel is igniting when it is reintroduced to oxygen at the tip. Similar to how a cat converter works.

The end result is awesome!!
