Does anyone know if a header back package from a g-body would fit on a b-body?

If anyone has tried swapping a g-body exhaust setup to a b-body could you post up some info.

 

I don't know about headers for the B-bodies. But I have a dual exhaust on my wagon using the stock exhaust manifolds and it sounds much better and performs better. I did have to custom fab an dual hump cross member.
