Question on LT1 v LT4 OEM Cat Converter Compatibility

Question - Are the LT1 and LT4 primary cats the same?

Before everyone says just do headers, I want to get the chassis sorted before more adding more power, as of right now it has plenty.

They are not the same part numbers. So I would assume they’re different.

I did see that, but also read that everything was interchangeable. The main issue is used availability used.
