4" Exhaust intalled/ oil/soot filmed after drive
I just had a 4" exhaust installed today. I drove about 30 miles with it. When I got home you could take your finger and wipe black oil/soot? from end of tail pipe. What do you think. I have stock injectors.

usually any new metal item is covered in a fine layer of oil to prevent rust, or lube from the tube bender is in there..... wipe it down, go out and enjoy your truck, most likely nothing wrong with it at all.
