hello there, i was wondering for CA cars including my 97 ls400, is the center middle piece after the two cats is considered to be the resonator or 3rd cat? i happened to get that replaced with a straight pipe but still have my two cats and the two resonators with muffler so i was wondering if it was okay and will i still pass smog? thanks in advanced.

From what I can remember from another post, you should be just fine.

varies but either way you won't get dinged on smog because techs don't look for it as it's not monitored by the ECU.

I did the same to my center resonator. That's really what it is... All the sensors are in front of it & should not affect emissions.
