ebay turbo headers
http://www.shender4.com/gage_chart.htm
I didn’t know gage thickness changed with the material? But according to this chart 18g SS is .050. 16g is .063. I’d be happy with 16g if I could find it.

When I was building my house I hired an old timer concrete guy. One day we were talking about my concrete walls & cracking. He said "There are two kinds of concrete: Concrete that has cracked & concrete that hasn't cracked yet." I thought for a few seconds then responded, "So it's like turbo headers?"
Supported, unsupported, eventually thermal fatigue will have its way with your manifolds/headers. Drive it long enough, hard enough, it is very likely to happen. My T-type had cracked headers when I bought it. I have seen many cracked DSM manifolds & have had one turbo system blow out a primary close to the head. I have countless other manifold issues I could throw out there like warped flanges on My Cummins diesel & on & on.
I just watched that video of Nacho's turbo Camaro on the main page & IIRC he said in the video the headers were Inconel. The best of the best. Well, if you watch the video during the second pull you will see the collectors start glowing then right at the top end of the second pull you will see a flash out of the drivers collector & then it gets shut down. Maybe he noticed it, maybe not, but that primary merger has been ruptured & will get worse & worse if they didn't catch it & fix it.

Are you 100% sure that was exhaust leaving the pipe though?

Yeah man. Look at the extra video that shows when it stops playing. It is a video from the guy you see videoing in the first video. He is standing right over the drivers side when it pops at 1:35 & you see the flame flash coming out of the primary merger.

I'd say weight savings and a collector type design VS the log would be the best reasons to change. But those 17g headers have primaries and collectors that are too large for what most of us are doing. I was trying to find something like these with a decent gage tubing and having no luck.

My biggest concern is cast flanges warping if the metal is right, which it appears they got it pretty good with how they are lasting people. Every 5.3 I've seen has had at least A couple busted studs.
Those are basically what I did a majority of systems with back in the day... Just flip those upside down & weld a connector pipe. I had 1-5/8" on my 5.3 as well. Torn between something like these or do truck manifolds.

IMO (if welded correctly) the cast OEM manifolds are the least likely to crack. Most of them are already 10-15 years old when we get our hands on'm and start bastardizing them. I've yet to see one crack...even with poor welding technique.

I have zero doubt a 1 5/8 “collector style” header with 2.5” collectors (or smaller 2.25”) Would outperform an OEM log.
I don’t think they are as durable or hold in heat as well. There’s usually enough “meat” on the OEM flange that you can machine, belt sand, or in my case block sand (ug..
) the surface pretty darn flat. I also admit I like the look of the aftermarket manifolds better.

I am glad you say they will last because with as thin as they are I figured they would just melt if I wrapped them. Awesome people are having good luck with them. Right now my turbos are not supported and you can move it roughly a 1/4 inch. I figured with the price you cant go wrong though!
