Catalytic Converter to Y-Pipe Studs

[K1ng0011]

I have a 1999 Ford Explorer Sport with the 4.0 OHV engine. I had two of the studs that connect the catalytic converter to the y-pipe brake off. Are the studs screwed in or pressed into the catalytic converter? I need to know if I need to hammer or unscrew the studs.

Pressed with a rivet style head.

Hope that helps -

I can confirm the original bolts in the catalytic converter are splined. They do not have threads so you can knock them out with a large hammer. I did so today
