Side note...I decided to list the K5 truck on Ebay again. I can't possibly enjoy keeping up with all 3 of them anymore, at least one of them needs to go!



Alright. I have another noob question. What is the name of this type of flange connection? I have both a flare for the flange, and a piece of straight pipe sticking into the manifold. I'm sure I could get away with a normal flare flange, but I have not yet been able to figure out what I'm looking at. I think it's a flare with a piece of pipe and a gasket inserted into the opening, but I haven't found anything similar in the exhaust catalogs.

Pretty sure the old exhaust donut is stuck in the flare.
Your finding out why the ATS setup wasn't as popular as the banks one.
It kinda looks like that, but it sure is firmly attached. And the gasket material has collapsed down to a rock-hard substance, despite looking like fiberglass.
I don't understand the popularity comment. The Banks system has better flow, but I have no idea which company had better support 30 years ago. If you handed me a random Banks manifold I'd be going through exactly the same problems (though Banks still has a parts catalog today, so that would be a plus). I'm assuming that both kits originally came with all their pieces.
Both ATS and Banks made turbo kits for both Ford and GM. Banks was more of a known brand I think and they could be dealer installed on GM truck's too. Which hales them be better know. I think it was a better fitting system also.
I see what you are saying now. You might be able to make it work. But I can’t guarantee the pipe would even be round in that area. The cross section might even be square, that’s how much this down pipe is massaged.






I’m running an oldie. It’s the same as the current 14066255 version.

10-4. $100+ is pretty steep for an actuator. I think I'll check mine rather than replacing it preemptively. It's pretty easy to access later if it breaks.
