Water comes from my exhaust and not very little

Hello fans, I have a present for you again for Easter and this is a problem? if it is one. 2 days ago when I drove in my underground garage and ran up I saw a mega water track, real thick klekse and drip exactly where I drove.. up to my parking space. I didn’t think about anything, the next morning I checked my cooling water but everything ok and dense. Am today over 100KM danger and no problems so I thought ok the Track doesn’t belong to me Today I went to my fitness studio and my girlfriend with her car behind me, and she then said that I lost the worst water. Then we looked a bit more closely and it turns out that it comes from my exhaust. What could that be now? what bad? or is that normal and some kondeswasser? Driving he does himself quite normal and the engine Temp is also completely ok. But somewhere the mega water track has to come from?? =) Lg
