Catalytic converter piping? Single or double wall?

As the title states... I want to cut off the rusted and leaking flange joint off the end of the cat and weld in a straight connector and be done with it and if it is a double wall, would I have issues doing it the way I want to?

Edit: I have an 03 with a 3.0.

Double walled exhaust pipes are used to keep exhaust hot enough to get cat converter full function.
It also reduces heat exposure to adjacent wires or parts.

So you should stick with double wall, especially if you need to pass emissions tests.

If it is just a short connection it probably would be fine but I am not there you are :) so can't say for sure

I plan to cut it off as close to the flange as possible to avoid cutting into the double wall. But if I have to cut into the double wall part, do I have to close the double wall up or can I just install my connector over it and let the exhaust gases go inside the space between the two pipes? Would that cause any issues?
