NSX Suspect exhaust header adapter (gasket) failure

[Japanese30]

Hi everyone,
I am proud of my 1993 NSX, and I totally love it! Of course, I understand the age and stuff, but I do everything needed to keep it in the top shape. Now, something went wrong about the exhaust gaskets or maybe some pipe failed, as some exhaust gasses do not flow as they are supposed to, but get under the hood, which throws up errors...
And to my understanding, it is either a header adapter or the gasket between the pipe and the adapter...
I was wondering, if any of you folks tried out the aftermarket adapters on your Acuras (I've got aftermarket catback, but the rest is still OE)...
Any ideas are appreciated!

An update - decided to give it a try and ordered an aftermarket exhaust pipe adapter for my NSX (https://www.carid.com/1993-acura-nsx-exhaust-pipes/). It should come with the gasket, so decided to replace what I've got...

Keep us posted on your findings. I have a cat-back and looking to replace the b-pipe too.
