Early Caymans with different catalystic converters?

Hello all

I get the occasional engine management light every few thousand miles which I suspect is a dodgey Lambda sensor.
While I was researching it I came across some information on the American forums. Apparently early Cayman were fitted with 400 cell cats which caused engine management lights which caused Porsche to swap them to 600 cell cats in later models. As I own an early Cayman (Mid-06) I thought I'd ask.

So just out of interest, is this true?

Thanks :)
