Performance headers and O2 sensors ?
Hello,
I would like to instal performance headers without CAT. My car has the catalytic converters only on the original headers. Please see the picture below. My question is: Do you know how to replace the secondary O2 sensors? Are there any simulators on the market for the BMW 330i? I found just for the 335i. I am looking forward for any help!  |
