Just a question, but if I were to eliminate the cats right after the manifold, will the O2 sensors still be ok screwed into the bungs? I have a crazy rattle in one of the cats, and I can feel it bogging down a bit. If I leave the O2 sensors where they are, with the cats being deleted, I assume it will run just fine. correct? Thanks for the suggestions/input. This is in regards to my 1990 XR7 Supercharged 5spd.
