if you don't want to sacrifice power, you can also got a higher flowing catalytic converter such as carsound.

Type 1 Racing has one as well for the JDM ITR fit. It's basically a huge resonator, as all of the catalyst is on the outside of exhaust stream. I'd suggest maybe switching to a quieter exhaust, or paying the ticket and trying to stay out of the throttle while in town.
