I'd guess that piece is to fool the ECU that there is a cat on the car when there really is not. Just a guess.... :crazy:

All you need is a $3 18mm spark plug spacer on the bottom o2 sensor to fool the car into thinking there's a full cat in there. I did this with my Akrapovic DP on my Countryman and 20k miles later still not one CEL

Yes to trick the ECU about the hi flow cat.
