from my understanding, there's three versions (possibly 4?)

v1 is the first, obviously, which is polished and without mounting tabs. resonators are filled with fiberglass for added rasp reduction

v2 comes next, the fiberglass was removed and it was coated in some kind of different grey material

v3 added mounting tabs

then i think they went with a different gasket type.
