Gutted cat with test pipe welded inside?

Who is running a gutted cat with a pipe welded inside? I'm in NJ would like to run a test pipe but don't want to not have a cat on the car ( with my luck a cop will impound it). Will the car pass NJ emissions with maybe an emissions chip and no cat?

It depends on the rest of your setup. You will also need your EGR working and not blocked.
Ed--Do you think my car would pass with a gutted cat and a Bob Bailey emissions chip? My EGR is functional. I really hate taking off the gutted cat once a year to put on a 'real' one for emissions. Thanks for your opinion.
I'm not sure how NC is on the visual but it should pass. It helps to get the car real hot
200-210 for the test. Fresh plugs,O2 and oil change will help too.
I passed with a gutted cat, stock chip, and a paperclip in the ALDL putting into diagnostic mode. It worked. Nothing else done special; this was in Ft. Lauderdale.
Thanks Ed/John. I may try it next year with the gutted cat, just to see how it does. Worst that could happen is I bring the car home and put the real cc on.
