I installed the Mountune downpipe and catback combo over the last week. Once I got it all back together and started it up, water was dripping out from the downpipe to catback connection (where the gasket is). I shut it off, let it cool, and tightened as much as I could, but it still has water dripping from it when the car is warming up. Should I be concerned with this? I can't hear any exhaust leak, just the water drips.
