Pull rear O2 and tie to frame rail. No sim needed.

Ran both my '99 R/T and my '00 R/T for years with the O2 tied to frame with zero codes ever.

What does tucking the 02 sensor do? Allow for you to run without the cat or what? What if you have to get your vehicle inspected every year will the shop still pass it like that
