My 2017 recently began spitting more soot-like water from the inside pipes than usual. Startups can get a little smokey for a few revs until it burns off. Anyone else experience same? I need to put down cardboard in the back so it doesn't stain my garage floor.
Exhaust spitting sooty water

Chemistry
Hi,
This is normal chemistry in the exhaust. Part of the catalyst process H2O is produced as any-product in the exhaust (prime reasons behind stainless steal exhaust components). It will stain chrome if not cleaned regularly. It will increase in humid areas and more noticeable on cold start up since exhaust will also build moisture on its interior when sitting which has to evaporate out once engine starts building heat in exhaust system.
No worries, enjoy your ride.

Thanks, Jim! You're spot on. Mechanic at Ford said the changing season in MN and the fact that I've taken it on some short rides recently makes it more noticeable.
Great info, Jim.... same is happening with me, and the humid weather lately here in SoCal.... gotta make sure to wipe off those exhaust tips once in a while!
