Yup. Got it myself.

There is a 2-piece clamp that holds the center pipe onto the cat.
The bolts get broken, letting the clamp rattle on the pipe.

The clamp looks like two rounded triangles, with bolts in each corner.
They squeeze the flanged pipes together with a gasket in between.
Do you notice exhaust noise? Some leaks out between the pipes when
the clamp is loose.

Mine is currently "fixed" with a piece of wire twisted around the
clamps (only half of my bolt broke off !#@*!@**&!@^#*&!@#&!*@&#!).

Only my cat shares my opinions, and she's too heavy to care.
