The Bassani is "50 state legal" for emissions reasons only. That claim has NOTHING to do with complying with local exhaust noise regulations.
First thing to do is put the resonator tips back in - that should quiet it down significantly. Then demonstrate the sound to the officer outside court, or at his station. Maybe he'll let the ticket go when you do that.
If that doesn't work, bring the SVT supplement in to show the judge, and explain that the exhaust is how the car came stock. (Comitting perjury at your own risk.) That has worked in the past with other people.
