I forgot what it means when the exhaust has water trickling out of it. I think I remember but want your version before I slash me wrists.

Engine cold? If so, it is normal until the exhaust system warms.

If it does it all the time, engine hot, it's a problem. Check coolant level often.

Max is spot on!
Cars blow water out the exhaust, "I think" its condensation from the hot fumes on the cold walls of the exhaust.
This also explains why exhausts rust out quickly on cars used for many short trips.

Thanks thought it was more serious than that. It only does it when cold so will keep a check on water as advised.
