No. Look just like them. I would think they are are Bavarian Motor Sport but can't be sure. They are nicely made, real clean welds, and came off an early e12 which fitment is fine on an E9. I have probably sold a 1/2 dozen sets of various headers here, some from e28s and no one has had a fitment problem that I am aware of. If you'd like send me an E mail address and I will haul them out and get a picture for you later
