the service manual states that the middle pipe is not intended to come off after being fitted to the muffler. If you take it loose they will never seal to each other again. While Mazda sells them separately, they recommend replacing both pieces if either one is needed. It's easier to ship them separately.
If you're trying to make a different exhaust using the middle pipe you're better off buying a new one unless you don't have any intention of using the OE muffler can again. Then you might as well just cut it off above the joint because that connection is a slip joint for 60mm OD tube and doesn't mate up to the typical US tube sizes anyways.
