How many catalytic converters are on a 2001 Boxster S?

the real question would be are the rear cats monitored? a lot of cars only monitor the front cats for performance? the rear cats are NOT always monitored...so they could go and not create a CEL. To know the answer, just look at the position of the second O2 sensors in relation to the rear cats...if they are before...no issue to remove them, if they are after the second cat? you get CEL if they are deleted

Thanks!
I did see this image yesterday in one of the other forums, so this does give me more of a feelgood on this.
This was corroborated by a couple of Porsche specialists I spoke to, although of course none would guarantee that the car will pass...
Car is getting PPI locally to the seller, and after that I hope things will move fast.
