110miles and exhaust tip is black

[SethSwitch]

Hello All,
I have a 2010 tahoe 5.3 and am getting lots of soot in my tail pipe. Washed the vehicle yesterday and after 110 miles of driving the exhaust pipe is covered in soot. It consumes about 1 quart every 5,000 miles so not terrible. It has a catch can, cai, magna flow, and tune. I have always had great oil pressure and run full synthetic with the acdelco filter. What do y'all recommend I do? Don't want this to become a big issue if I can get it fixed now.

Sounds like it might be running a little rich.

It's sooty on the outside? Do a lot of city driving?
