No problem, here is a link that shows the entire exhaust system. The dealer was able to order only the parts I needed which was #5202 exhaust extension, #5H211 rear exhaust pipe, and #5A231 exhaust clamp.

I'm assuming your 2021 was built on a 2020 chassis the same as mine and most other 2021's. Good luck...I think I'd try a different Ford dealer or at least a different parts person.
