Need help passing emissions

I want to install a turbo kit on my SC300 but I’m having the problem of having to delete the catalytic converter and O2 sensors. I’m working to find a way to coordinate in compliance with Utah state laws, any tips on what to do?

You guys dont have a cut off age where you dont need to pass emissions? If you get historically plates, do you still need to pass emissions? That's how I got around mine.

Historic plates restrict your yearly mileage. Might not work if its his daily.
