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.

Two O2 sensors one before the O2 sensor and one after.

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.
