Default Exhaust Smell and Rattling

I got a P0420 so I took my car into the dealer and they replaced my cat for free since it was under warranty but now I can smell exhaust when idling and there is a rattling sound at about 3k rpms. Any ideas?

Does the rattling get louder as u go faster? I'd check for loose heat shield.

I'd say take it back in before you do anything else and explain the situation, they would atleast check it out free of charge since it didn't do that before they replaced the cat
