I will say X pipe is cat back system. Unless you are talking about axle back?

From the primary/main cats to the back. I think most people don't really acknowledge the secondary cats when talking exhaust. They are un-monitored and not normally something you would consider.

x-pipe would just be x-pipe. Catback means that you're replacing everything from the primary cats and further.

So the second one could be removed with no issues on a header to muffler system?

Correct. Mine are off now. Our stock system is basically a one-piece unit from the tips to the secondary cats. Unless you want to do some cutting, it all comes off as one unit, ending at the primary cats/headers. There's no monitoring on the secondary cats, so there's no consequence to removing them, unless you need to pass California emissions.

Here’s a pic of stock cat back.

Seeing it like this makes it seem like it's not that difficult to swap out... Even with the car just on ramps

Probably just need a second person to help hold it

I did it by myself with a jack and 4 stands. Ramps will be much better!

X pipe is after Cat so Catback exhaust system means included X pipe to muffler.
