Are the upstream and downstream Lambda sensors both the same? I'm wanting to use my old manifold lambda sensor in my decat pipe insert. Are the connectors different or anything?
Thanks

Well one is a for before cat and the other is for after cat. The after cat one should read clean and is usually a blue plug. I think single plugs are sometimes both grey plugs though. They aren't interchangeable to my knowledge no.
So as long as you're using your dirty lambda in the cat and sleeve the clean air one that should be fine.
