More euro header questions

[Bostonbruck]

I have fully removed my oem headers and will be installing euro headers. Is a euro section 1 required or can I use oem? Do I delete 2 of the o2 sensors? I know this info would’ve been on the m3forum, and I just can’t find much info on it. Any information will help me greatly since I am still confused on what to do. Hopefully I will get this done soon. Thanks

I believe you will need to code out the EGT if you’re planning to use your “stock” sec 1. Same with the rear o2s (will need to be deleted/code out)

Wow, cant believe I accidentally posted this in the Parts for sale forum. Someone please move it to the correct e46 discussion forum.

Thanks for the response. I think i will block off the EGT and do exactly what you said.

Yeah I believe you can do it with Martyns tool.
