2 questions

1) will you have to use the e36 headstuds? it looks much thicker at the flange than the e46/z4m style header flange
2) what is that last picture of? it looks like the o2 threads into the header?

1) I will try them with the OEM Z4MC studs first and will get E36 studs if it doesn't fit. It's not supposed to require longer studs.

2) This is locate on the post cats, it's supposed to avoid CEL, will see if it really work. But I'm not sure exactly how my ESS VT-445 software is tune right now so maybe I won't have any CEL anyway...

Are those the VAC budget headers? They are selling them for $670 here.
If I can get a guarantee of fitment Im going for them. $200-$300 difference, I don't believe there would be much difference in performance.

Heres the VAC-Fabspeed ones for $899 if they get GB pricing. Not sure the difference between the two.

Here are pics of the VAC/Fabspeed ones installed. Sweet

They are the Fabspeed headers, purchased directly from Fabspeed before VAC Motorsport got the exclusivity of selling them.

I was going to buy the VAC budget headers but my local shop had the Fabspeed in stock for a good price.

And when we called last week at VAC, the guy recommend the Fabspeed over the VAC budget headers...

I'm pretty sure the VAC budget fitment isn't that bad at all.
