Today, while changing the oil, or I should say filling back up- I found some dirty soot building up in this area. I also found it behind the air filter housing on the firewall in slightly heavier amounts. Down pipe and straight pipe are shiny clean. Is this normal to happen in these 2 spots?

Yes. Looking at the front of the truck-top left.
