Exclamation 2002 Mustang GT Emissions Fail! HELP!

Hi everyone. I am looking for advise on how to pass emissions in Chicago, IL with my '02 GT. It was modified and tuned by Sutton HP which is no longer in business. I have Bassani mid-length headers, a Bassani X-pipe w/no cats, and a Magnaflow cat-back. The passed emissions successfully for years post modifications, but apparently the state of IL has made the testing more strict and now no matter what I do it won't pass. What can I do in order to pass emissions with my car? Please help....

You think you can keep up w/me? Others have wrecked trying! '06 Gixxer 1000 and '16 KRT ZX-10R.

Please elaborate more on why it's not passing....

Are you failing a visual check? Or what code is being tripped on an OBD2 scanner that the state computer is not liking? Do you own or have access to an OBD2 scanner? If you do, scan the car and post up the codes.
