If you follow everything correctly, you wont have CEL.

EDIT: Here is another source with all the parts you need. + the bungs I already sent you the link for earlier

Ahh I see, thanks a lot. I don't know, this is all still chunking into a possible supercharger install I'd like to do. I'll think about it, thanks for the help everyone and best of luck to the seller of course.

I just thought of something else though. With the midpipe you just sent me Schmoupe, would I even have any cats by buying these headers? Does the Z4M have THREE cat sections on it?

Speaking of that seller, please don't apologize for your English. I wish I wrote/spoke German as well as you apparently do English!
