I'm looking for N52 headers for my 07' 328i, and I found these which are ~$150 cheaper than their next cheapest knock-off competitor on AliExpress:

I'm inquiring to see if anyone here has bought these?

The SS material used doesn't look as good as the next price up, the welds don't appear as refined, and I'm curious if the overall fitment is an issue or not, along with the o2 bung placement.

With only 2x positive non-reviews I'm wondering why these aren't more prevalent in the E90 circles (they claim 19 sold), and that this is one of those products that you get what you pay for. In my experience buying a header that does not fit well enables hair loss, but if they fit well I'll buy these in a heartbeat.

Anyone care to comment based on their experience buying these specific headers?

There is an old post here, that says that these types of headers are no good because the o2 bung placement is bad. It only reads cylinders 2 and 5.

Thank you very much for your input, this is exactly what I was hoping for . As expected I thought there might be a catch, as you get what you pay for with the cheapest header. Will avoid purchasing now, and pay more for a better header.
