Why is there water dripping from my catalytic converter?

I noticed a small puddle towards the rear of my vehicle, so I took a look, and it was coming from my catalytic converter. Why is there water dripping from my catalytic converter?

Not to worry; water dripping from your catalytic converter does not indicate a problem. The entire job of your catalytic converter is to transform the most toxic parts of your engine’s exhaust (like smoke) into something more environmentally friendly (like steam). Water dripping from your catalytic converter means that it’s doing its job of creating steam—no need to call your mechanic.
Although there’s nothing wrong with water dripping from a catalytic converter, it can really ruin your day if you notice other things dripping from your car that shouldn’t be. If you notice any fluid that’s green, pink, or yellow, be sure to take your car to a mechanic.
