Disconnect the harnesses. On the front harness on one side you will have to remove a little cover to access the connector.

Disconnect rear band clamps.

Disconnect header to midpipe. Hard to get inverted torx fitting in there. You will have to be patient. A flex head 10 mm ratcheting wrench can work. Beware there is a fiber cone gasket on the end of the header (or maybe stuck to the midpipe flange that you will have to replace if you break it).

Before totally removing front connections, go to the rear and put a jack stand or block of wood or other support under that end that you can later push out of the way with your feet. Then undo the middle support. It will stay stuck to the x pipe and that is fine.

Then go back to the front and fully disconnect and wiggle the x pipe off the headers. As you hold it, push your rear support out of the way and lower x pipe to the ground and pull it out from under the car.

Thank you so much for your help. I'll try and tackle it today. I really appreciate it!
