Default 1 month old cat broken?

Anyone ever have a brand new cat converter go bad on them? I just had magnaflow cats installed with my long tubes a month ago, and last week, the exhaust start making a horrible rattling sound. The exhaust shop guys looked under the car. No leaks, pipes weren't hitting anywhere. He knocked on the pipes and we heard the rattling coming from inside the passenger side cat. I've never heard of a cat problem like this, so I am curious as to if anyone else has heard of this.

SLP full exhaust, Stainless Works LT's, Monster Stage 2, Tick TorqueMAX 231/235 .61/.62 111+2

Yes. And it was aftermarket cats too. Don't remember the brand though. I'd be contacting magnaflow ASAP.
