Did your CAT rattle all the time? When hit with an object?

My 2002 2.7L has an exhaust noise/rattle that occurs during acceleration once the exhaust warms up for about 10 minutes. When it's cold I can't make anything rattle when smacking with a rubber mallet. Heat shields are tight, so I'm thinking the matrix detaches from the CAT body when things heat up.

I think it rattled already when I bought the car but iut wasn't so obvious because of all the other noises But it got progressively worse also. It was better when cold and was gotten louder with the engine warming up.
