Default Do I have a GMS MAF?

i just picked up a 99 WS6 and the first thing i noticed when i popped the hood was the MAF ends are black. i took the MAF off and saw a GMS sticker on the outside of the MAF and its descreened with smooth ends, but the sensor itself on the inside looks like a stock MAF thats had the supports cut out.

is this how the GMS MAFs are or did someone modify the stock MAF, add ported ends, then slap a GMS sticker onto the MAF.

the thing that bothers me is the sensor supports literally look cut out, like someone just snipped em with dikes or something.
