I remember the thread, but I cant find it. What I did find was a 328i race car using supersprint headers.
You're going to have to show me the matching part numbers...Im not finding it. The pic you used is a generic one from BMW. Check realoem and you'll see it is reused on every n51/2/3 diagram euro or us spec...even on my 9/05 325i which I know doesnt have that manifold.
euro 325i n53
us spec cars
328i (I see the part number change, but dont see any difference while googling it.)
Even Penske parts reuses the image...
