Simple question. Planning on having a catted x-pipe but its stock for now. Will it pass with either setup? I've heard as long as you have cats you'll pass. Yes this is a D/D and I'm in IL. 
Can 5.0s pass emissions w/o smog pump but/cats?

I dont have cat or pump and i fail HC at idle and Pass everything at cruise. Note: my engine runs like **** at idle right now and i have issues. I dont live in a emission attainment area so it doesnt affect me. I just took it to work and put it on the 4 gas for curiosity. On other hand my friends 5.0 with no cats but smog pump passed with flying colors.
I live in Illinois too in the Naperville area I run a O/R h-pipe with no cats I havent had an emissions test done on it because I knew it would never pass so I just registered my car to a P.O. box in a far far west suburb that doesnt require emissions testing. Its probably not very legal way to do it but oh well. I know this is no help to you but thought I would chime in.

The airpump is old emmisions technology designed to assist the cats. On a proper working engine they are not needed. Also, if you have aftermarket cats, the airpump is just wasted weight. It does effect the computer and will show a code, but no check engine light.

I have nothing productive to add!
I have never personally had an issue with noit having an airpump but having cats and passing emissions.
I've been running without an air pump for over 20k miles. No problems at all. This is with a Bassani high flow x-pipe.

I used to pass every year like that when I lived in Florida and when they had emissions. I would bolt on the CATS once a year, drive to the emissions station, pass, and drive home and take them off and store them until the next year. I never went through the trouble of bolting up the smog pump.
Then Florida realized that emissions testing was a waste of time and money and scratched the whole thing.
Now I moved to Dallas and here we go again. Now only if they would realize the waste of time and money we would be OK......

Depending on what they look for during the visual inspection it could be a problem.
