High Flow Cats
I have a 2019 Z06 and I am wanting to install headers and X-Pipe. I'm and about to move to a state that has emissions inspections, so does anyone have any experience with "High Flow Cats" on the X-Pipes being good enough to pass an emissions test?

They are secondary cats not resonators.
It's why Cat buyers will purchase them when you take them off.

As long as your destination county/state doesn't do "visual" inspections and look specifically for secondary cats, you will be fine deleting the rear cats or installing an X pipe with high flow cats. The front cats are monitored and cannot be tampered with in states that require emission inspections. If your state just does the plug in OBD2 inspection test, then you will have no issues with rear cat deletes or aftermarket X pipes.

It really depends on how your region does testing, it varies widely. Visual, OBDII, sniffer etc
