I am still waiting on the official ruling from Carter. I was told to go ahead and post this information.
Here is a fix for the broken exhaust flex.
Cut the factory flex at the welds. I purchased a Marwell flex FT13404 which cost $46.00. This flex had necks on it so I cut them at flex. You should be able to order the flex with no necks. Have the muffler shop bump up the flex so that it just fits the pipe. Bolt the down tubes in place and tack weld the flex. Then remove the pipes and completely weld. See pictures.
