OEM o2 sensor doesnt fit cat
So awhile back I redid my exhaust. before it was header to straight pipe to muffler. I changed it to 4-2-1 header to cat to pipe - muffler. Got my primary o2 sensor on just fine but I the o2 sensor wont fit on the cat. its too big. what are my options? im in jersey so this is just to pass emissions ( the right way this time lol) My header does have a spot for another o2 sensor but im assuming having both the primary and secondary sensors before the cat will still throw a cel? any help is appreciated.

just get a new one off ebay for 30-40$ or go to the junk yard. other potion is get a different CAT strange that the thread pitch is different if it was meant for your car,

im thinking if I can find a non fouler that fits this smaller o2 bung on that cat i could still make it work. its a longshot but ill look into it. buying a new cat is too much hassle. this one isnt even 6 months old.
