I bought these headers many years ago. Standard euro headers I think, yes? How can you tell standard vs CSL? So long ago I'm embarrassed to say I can't remember for sure, but I'm nearly 100% they are not CSL.

What was the euro spec exhaust layout? Would it have been these headers, catted section 1, x-pipe with resonator and stock mufflers? We're the stock euro Z4s louder by default then, not having the cats in the headers?

Regarding section 1, and I admit ignorance here, would it be possible to run small resonators upstream of the cats? I know space is tight, not sure what that would do to cat functioning.
