For the Y-pipe I was a little better prepared. I've done a few jobs welding cast over the years. So I broke out some Jupiter Rod left over from an old job and buttered the top before attaching a V-band flange. Here it sits after a full night of being buried in the sand (After full pre-heat and post heat).

Test fit of the band so I could install and run the rest of the tube up to the turbo.

I don't recommend it, but I was able to piece the up-pipe together one piece at a time in the truck.
I ported out every piece; here is a shot before it was quite finished:

Funny enough, I actually ended up using a copper seal in the end!
These v-band flanges came from Monkeyfab - this a picture from their site. I forgot to get any pics of them.
You anneal the ring before install or re-tighten it after getting your exhaust hot. I chose to pre-anneal and I've had zero leaks in the 50-60 miles I've driven on it so far. (I crawled under to check a few times this week)
