So I managed to cut off 3 of the studs. But the whole thing still isn't budging, as it seems that the two flanges and gasket are all fused together by rust. Lowering my jack and putting the weight of the exhaust on that connection did nothing.
Going to get a better sawzall blade tomorrow and hack off the fourth nut/stud. Then I'll use a chisel or perhaps even cut into the rear flange to try to get some leverage and pry them apart.
Between the cats and o2 sensors I'm reluctant to use too much heat or brute force in that area...
