Hey guys,

I just purchased a set of European headers of a 2002 E46 M3. They should arrive Friday, I got them from an English parts yard for 567 shipped. They are coming with the primary (first) oxygen sensors.

I would really like to get a hold of the Europe section 2, but this is proving to be a challenge. I saw the write ups on the addition of the O2 sensor and EGT bungs.

My question is, besides the bungs, is the European section 2 any different? Bigger cats?

Also for the people who have done this mod, where did you purchase the O2 bungs?

Also, when my brother eliminated the catalyst on his E46 M3, the car stunk! I don't believe M3's have secondary cats. Can I expect the smell of fuel?

And finally, will the car pass smog? I am not worried about the visual.

Thanks!
