Exhaust Removal Question - 93 400e

[90free400e]

i was attempting to remove my exhaust from the cat back today. Unbolted both of the clamps that *i thought* were the only things holding the pipes together. However, upon unbolting, the pipes still wouldnt seperate from the cats. At first glance i thought it was welded, but i sort of got the left one to budge. However, the 2nd one WILL NOT MOVE. Anybody have any suggestions on how to get them apart withouht cutting? The car has 215,000 miles on it so i think they may just be rusted, but i could use some pointers. Thanks.
