Default Oem csl headers

Hey guys i just purchased OEM CSL headers from M3 Nut. I want some advice from others and want to know if these part numbers are correct and they are the Real OEM CSL headers. Also You see those two last pictures that have the rust all over them? You think thats Useable and acceptable.

Let me know
Thanks
Eric,

Part number: 7 833-501-23
KW 27/03 for the smaller header.


Part number: 7 833-500-03
KW 26/03 for the bigger header.



Are these real OEM CSL headers???

Real or not, this looks old and not powder coated. Didn't you check it out before you buy it? You really don't want to go back after you install it. It was painful for me to install this header. It took me and my buddy 6 hours.

It does have the roundel engraved, so that is good. I don't think they're CSL header's though.

Link to Real OEM: http://www.realoem.com/bmw/showparts...14&hg=11&fg=50

01 Exhaust Manifold Front ZYL.1-3 1 11627833500 $1,125.61
02 Exhaust Manifold Rear ZYL.4-6 1 11627833501 $1,125.6

That gasket needs to be replaced, its only a few bucks, put new ones on.

You should also use that time to replace or upgrade your CPV o-ring while you're there.

Those gaskets are recommended to be replaced when installing headers. You need new nuts and studs when installing headers. Get the header install kit. Comes with all new gaskets, nuts, studs, and bolts needed for a tight seal. Also, they are most likely just the basic euro header and not from an actual CSL.
