I'm in Tennessee and I have emissions coming up. Just a obdII hook up but I have a x-cal2 program running with the rear o2's turned off cause of my catted x-pipe.

Am I gonna have problems?

Thanks
Josh

you'll pass if it is not a smog type test.

in NC you will pass as long as your CEL is off. i have my rear o2's, EGR and Evap systems turned off and i have no troubles.

I passed my inspection in NC with my Diablo Programmed. I don't have my 02's off though.

As long as you don't have more then 1 "not ready" signal from the computer you should pass.

The rear 02 sensors are there to monitor catalytic converter function only. If they are shut off in the tune then there will be no emissions 'hit' by leaving them off. If they are physically not there or the cats are gone, you may not pass a visual inspection, if they do a visual where you live.
