leak from exhaust installed my SLP Y pipe, got it bolted up, and now I get water coming out where the cat converter pipe meets the Y pipe. Just a few drops, but still, don't know if that is going to cause issues (mainly for annual vehicle inspection)
Water can most definitely come from the exhaust. It's called condensation. Look at a car that's been started first thing in the morning on a chilly day and you will see water dripping out of the muffler.
Some mufflers even come with a little hole drilled in it to drain water so it doesn't sit in there and rust the muffler from the inside out.

Not when it's dripping straight out of the catalytic converter. Condensation happens when exhaust cools thru a cold full-length exhaust. You will never see water dripping from a manifold or header. Not enough "space" to cool and condense moisture.
Also had water drip out of the headers of my 98 Camaro with a sbc before I put my exhaust on.
I could be wrong but both cars definitely do not have any type of coolant leaks

The only way that might happen is if the header/converter had condensation in it after a cool night, and it blew out upon startup. Exhaust is too hot coming out of the engine for any liquid moisture to form so close to the engine.
