This is the plug that came with my VRSF downpipes. It doesn't have the same kind of flange or the thread locker compound.
I think the older VRSFs downpipes came with a plug that looked like OP's with the washer, as my plug was like OP's IIRC.

This listing has the pic with a plug bolt with washer but it's hard to tell image isn't high res.
