Used headers brand?

[AZ-LSB-M3]

Hello, I just bought some catless headers on fb marketplace that were listed as “Active Autowerke” headers for $375 shipped. But as far as I’m aware, those headers are usually just reps of the euro headers. The headers I bought are not shortys but instead long tube and sort of look like Supersprint Stepped or CPI headers. Maybe even fabspeed but I don’t see any sort of branding that might lead me to believe they are Supersprint or Fabspeed. The welds are really clean and well done as well as the flanges that connect to the engine are separated instead of joined like ebay headers usually are. I believe there was an additional O2 bung welded on for some reason but other than that they are in great condition. Anyone have any thoughts on what these could be?

The design is Supersprint V2 stepped.

Since Supersprint usually have tags on them, they're probably CPI. CPI was a V2 knockoff.

CPI stepped headers - https://www.bimmerworld.com/Exhaust/...M3-Header.html

Basically SS V2 reps.
