My94T/A

I have a 94 T/A A4 with about 118000k on her. This is my frist F-body that I bought for myself. Well I am at College. Yesterday it snowned a bit in NJ. So I went to start up the car today and make sure the battery still has the juice. I let it run for few minutes and Then when the temp for to about say 160..I reved it to 2000rpm maybe twice. I don't go over that when the motor is cold. Well when I reved it there was like this wierd Water noise from the passenger side, from inside. well I did it again and that like noise was there...it felt like water or fluids were going down the pipe or something. Then i let it sit for a bit more and did it, it was gone. So should I be concerned or no?? I heard this noise before...when i drive and the engine isn't warmped up all the way?? When i looked out side the tail pipes had few drops on water in front of them. Both of them. Maybe 3 drops and Couldn't see anything else, its dark outside. Also the car is bone stock. What do you guys think please help. Thank you in advance.
