Since I went decat, the rattles dissapeared. Maybe the part of the cat?
Doubt it had anything physically to do with the cat and the loss of muffler rattles can be attributed to either:

1. the fact that you've added more noise by removing the cat and now you simply can't hear the rattles anymore due to the increase in exhaust volume

or

2. the reduced backpressure changed the exhaust resonance and the vibrations/rattles were coincidentally reduced as a result
