Welcome and congrats, ctrlraven! That Kodiak sure knows how to camouflage itself LOL. If the turbo piping tract shows nothing more than a misting of oil, and the intercooler is pretty clean, chances are the catch can is not needed. Are you familiar with catch cans in turbo applications?
Don't let the mileage deceive you, maintenance schedule-wise. Get all the fluids uptodate. If you DIY all the better

If not, hopefully your Lincoln dealership will accommodate the PTU/RDU fluid changes, I have heard of some that have done that. A couple of Ford dealerships as well, but that is rare.
Might need to at least mufflers and X-pipe to make a dent in the tomb of silence. Hopefully you won't need to add a resonator to kill unpleasant frequencies when you do free up the sound.
