High Flow Cats + Mini Cats = OB2 Ready?
It's well documented that mini cats/o2 extenders do not work in our M3 but what about pairing them with HFC?
I have Akra full exhaust with HFC and have been thinking about adding mini cats like these. https://www.fabspeed.com/universal-9...nverters-pair/ I understand these will not pass visual but will the combo setup allow O2 readiness and prevent CEL? |

So I have some insight on this. I run an aFe HFC X-pipe, and I was hoping to never trip the CEL. Well, I did, randomly. So initially I was going to order what the OP mentioned, but I never could get a hold of anyone to order them (you need the 45 degree vice the 90 and to get that you have to call and special order). After several attempts, I gave up.
After continuing my search, I found this: https://www.urotuning.com/products/u...iABEgI4CPD_BwE They are $40 each, so $80 for the pair. They were super-easy to install, but you have limited room due to the O2 sensor, which is why a 90 degree will NOT work. Also, these were really solid and good quality. Since the install, I have not triggered a CEL. So this might be something you want to try. |
Appreciate
