It could be as simple as improper rubber mounting was used or improper installation.
The cat converter quite heavy.normally have 2 mounting/ear left right.if no rubber mounting was used the engine vibration transfered exessively to exhaust and to the chasis.ask shop to included some free play or better mouting.
Last time I experience too tight of rubber mounting bracket at exhaust.the vibration translate to chasis vibration.after put some free play ,chasis vibration improved.
