I have an 07, from sifting through a sea of threads it seems the general agreement seems to be that my 07 2wd should have flow through resonators after my primary cats. Well while removing my exhaust up to the supposed "resonators" I find theyre not free flow, they have a honeycomb barrier inside of them. So....what are they?!?, cats or resonators? Either way, they're getting tampered with!! If they're cats can I gut them without failing Texas emission testing? If they are cats, I wanna gut em, if they're resonators, I'm gonna delete em, there's an o2 sensor in front of em, but not behind em. What's the deal???
