Default LS7 manifolds/cats install on a dry-sump LS3- Question

Gents, going to install stock LS7 manifolds, cats, & h-pipe on my '12 GS LS3 dry-sump, & have some questions;

Can the stock LS3 manifolds be removed, & LS7 manifolds installed, without disconnecting the dry-sump lines? If not, should I disconnect them at the dry-sump, or at the oil pan?

My used LS7 manifold's have never been disconnected from their cat'd downpipes either, & I'd prefer not to dissasemble them, buy new bolts, etc. Can they be installed as one unit, or do they need to be separated first?

The car will be on 4 jackstands, @ 16+" off the ground, not on a lift.

Deleted because I replied in tech section. No need for asking same question in BOTH areas, btw.

Thanks for that Chimazo. I'll assume you have a dry-sump GS, & if indeed you pulled out your stock manifolds & cats as one unit, then I should be able to put the LS7 system up in there.

I'd definitely prefer not to disconnect oil lines if I don't have to, but I'll hope for some more responses from the CF collective.
