I had a similar experience on my previous car after I removed the cats, I had a metallic rattling sound/vibration at low rpm, but I couldn't find any leaks or loose shields, see video below. It actually went away after a little while, I think it could be just the resonance/harmonics of the new piping close to the engine, mine seemed to go away after a few months after breaking it in.
