Removing the cats

I have a 2000 with the 4.0 that has the y-pipe with the two cats. I'm replacing them as they rotted to pieces and rattling like crazy. But, it looks like a tight fit trying to separate header from the cats. Is there anything I should know before I attempt it? Does the intake manifold need to be moved? I briefly tried to stick a wrench in there and the angle of the bolts holding the two together seems odd.
Thanks.

Oh very coy with the PB, but its more the angle. You need an open end box wrench to sorta fit in there because the bolts are so long, and upside down, they nearly touch the bottom of the intake manifold. So you can't fit a socket on there. It seems complicated for something so simple so I was hoping someone had some insight.

ah gotcha.. understand the placement of the bolts... can you use a dog bone? might allow you to get a ratchet in there....

I used 2 different things to remove mine: 1) a 15mm ratcheting box-end wrench, and 2) a 15mm swivel socket. You can't really fit a swivel extension PLUS a socket, but a 15mm swivel socket fit pretty good for me. Good luck, it's a little frustrating & takes some time.
