Mystery decat pipes

[16v_paddy]

I've acquired a couple of decat pipes from a job lot of bits but could do with some help to identify them.

1st off is this possible cup racer decat pipe - only say that because that's what's written on it in marker pen 😂

Then I've got this which I thought might be a 182 manifold link pipe for 172's & compared it with 1 that I've got but the flanges are completely different

I think I may have an idea what the long pipe is.
It looks similar to this from a 182
