Some early 2020 downpipes clocked the O2 sensor toward the block a bit too much. It was fine on the 2-port head, but on the 6-port head it places the O2 sensor dangerously close to the exhaust manifold. This was fixed on later versions and "2021" downpipes. I don't believe there's any reason a "2021" downpipe wouldn't work on a 2020, it's the other way around that can be problematic.
