Couple days ago my exhaust was deeper than normal and muffled, then engine light came on. DTC was bank 1 02sensor. Ended up being my passenger side cat had clogged and the honey comb inside had fallen into large chunks to where no airflow was passing through. Had the cat replaced and new upstream 02sensor and now it sounds like I have a brand new exhaust system and runs a whole lot better. "Obviously" lol
