Hi Everyone, this came out the exhaust of my Y62 patrol
I was positioning it in my garage; started and stopped the engine a couple of times
Then I noticed this, how concerned should I be
What is the reason for this? View attachment 541924

Looks like normal condensation

It's what usually rusts mufflers out. Exhaust not getting hot enough to dry out the condensation. It's normal.
