Mini O2 "catted"bungs
I just watched a review for a 2024 M4 where the guy was running catless downpipes and using some mini "CATTED" O2 bungs. He claims to have driven a couple of thousand miles with zero CELs. These are the items in question
ttp://www.bigdaddiesgarage.com/mini-cat-cel-fix.html Has anyone here used these and had any experience with them? I believe this topic was very briefly touched on before but didn't really go anywhere. Thanks. |

are you speaking of the standard o2 bung extensions or the one with an actual honeycomb inside? i had mixed experiences with the mini catted ones, some work, some don't, it all depends on how sensitive your o2 sensor range is with the car. some do too good of a job it makes the ecu think the o2 sensor is broken.
