On my 2000 the cat flange does have pressed in studs, I had to drill them out, only did one side. A real PITA. However the PET does show bolts and nuts so at some time they may have changed this. Not sure when or why.

One tip a mate gave me was to cut them flush on the side where the threads were ie the side where the gasket would sit, then drill a pilot hole part way into each stud to relieve a bit of pressure so that they can be tapped out. I might have a crack at doing it that way on the weekend since I have mine to do.

I drilled & hammered out the cat studs yesterday. I experimented a bit and found they were a lot easier to knock out once they were drilled about 80-90% through as per the attached pic. Other pics/details are on my 996 web.
