How many o2 sensor ?

FlowMK6

Ready to race!
Hi all, I received my USP High Flow Catalytic Converter and I'm going to install it this week (Maybe tomorrow). I would like to know how many o2 sensor a 2010 Golf 2.5 have ? I saw the USP Catalytic Converter have two o2 sensor port. But I think my golf only have one o2 sensor, will I need to something to fill the hole of the other o2 sensor port ?

Thanks you and have a nice day,
Kind regards.

P.S. Sorry for my foreign English.

There can be three. CBTA only has two oxygen sensors while CBUA has three. If there is a hole for a hose just before the throttle body, you have CBUA.
