Whoah.. Thats awesome man thanks! So the studs literally screw into the flange or? That is interesting. Maybe you are right. It does make sense. Thank you so much on this information. And thank you so much for reaching out to Benny. Hope to hear something back soon. I have been searching everywhere on the net' to find a picture of the catalytic converter flange to see the studs, but every picture I find shows the cat from the front.Almost looks like the stud is supposed to snap where it necks down.
