If your car is new like others have said you don't get "sniffed" just plugged into your OBD-II.

So as long as your tuner turned the codes off for catless (mine did) you will pass. They may say something about the visiual if they actually look. In my experience you can find the places (like others have said here) that will pass your visiual without saying anything.

In regards to why would you want to run catless it's an HP thing. They restrict HP so if you have mods then you want to remove them so you make even more HP.
