We tried to shake the whole pipe including the hfc and it is pretty solid. Yup I visually inspected the new cats before installation, everything was ok.

No Mike, nothing is hitting against something. The hfc including the midpipe just shakes at just 1800 rpm. Other rpm range is ok though. As soon as I passed by at that rpm range it vibrates/shakes the pipes.
