What's your argument then... that we have the official designated names mixed up? Do you expect people to refer to the primary cat delete as the "Catalytic Converter-Close-to-the-Engine" delete as that is what the BMW Aftersales training manual states it's called?
All I gathered from that page is that what we refer to the "secondary" cat is called the "main" cat in the manual. It doesn't state anything about actual flow characteristics between the two.
