Yes- Here's what's inside the original CR side pipe mufflers:
That is a picture of a WHOLE LOT of restriction, and of a lot of places where rust has probably eaten away one of the joints between the inner pieces- resulting in your rattle.
The good news is- You can live with it, for as long as you can live with it.
As the rust dissolves the inner steel away, it will just get blown out the end of the exhaust pipe.
If the sound doesn't bug you too bad, then you could let it go until the inner corrosion finally eats through the outer casing, or until one of the inner pieces gets so bad that it completely breaks loose and starts bouncing around in there like a marble in a soup can.
