The X-pipe can have cats on it...

Then you can have a cat-back which also has cats...

Does that replace the mufflers???

Or is the cat-back between the X-pipe and the mufflers?

Thanks for you patience...

A true o/r X or H takes off the cats and moves the balancing tube up there. That's why they flow so well.

A traditional cat-back is from beyond the mufflers to the tips.

You can get a catted X or H that goes where the o/r pipe would, right behing the headers, but has high flow cats that should pass sniffer emmisions. Passing a CA visual is a whole different story.
