EDIT : referring to Owen.C93's posted pictures.
I do believe its to be able to put a strip of material lenght ways from the top to the bottom to stop the exhaust distorting under heating. if also makes sure the flow is going straight, as so it flows "flat" on and under the diffuser rarther than spiraling out. Effectivly conditioning the exhaust flow before it leaves the pipes. You can just see where the strip is welded, straight through the circle, its the same underneath aswell. Its produces as a strap thats fitted after though and used to bolt it to the floor. Note how it is proud of the exhaust body itself
