Y-pipe bolts
 
I know this is a dead horse. I've researched the hell out of it and can't find a definitive answer to my question. Can this lead to serious engine damage?

My 2016 800 etec was ran with 3 y pipe bolts missing for possibly most of the season. Its my wive's sled. I rode it and found it would only pull 7600rpm. I adjusted the clickers and found 2 bolts missing from the y pipe and 1 backed out. I couldn't find one of the missing bolts... The clickers were set at 2 so I set them at 3.

Now it'll pull 8000 rpm but still seeing much less track speed than previously.

Is it possible I have some serious engine damage done to this sled??

It is possible that your gaskets are now shot and need to be replaced for the y-pipe. If that's not it of coarse snow conditions of a lot to do with track speed to. If the snow is wet and heavy that will slow your track speed down no matter what rpm your pulling. As far as engine damage I don't think you harmed it, I ran mine for 100+ miles not knowing the y-pipe was loose till the dealer found it and fixed it, never hurt my motor it still runs good as ever.

I checked compression, its sitting at 130psi on each cylinder. I'm at about 2000' above elevation.. Is this a good number?

Yes 130psi is good your fine.

this has been a problem from 08 up. The factory should have addressed this by now IMO! And it is a PITA to tighten them.
