I am getting ready to install my Berk High Flow Cats and I have a question. There are 2 o2 bungs in each HFC, my question is which bung do I install my o2 sensor in, the short bung or the tall bung? I looked at the instructions and could not find anything about this. I only have a Pop Charger and Borla TD installed so far but I will be putting in a Plenum spacer in a few weeks (if any of that matters as to which bung my o2 sensor goes into) Thanks much!!

I recall reading a recent thread on here where someone posed the question to Berk. They said to install in the long bung. If I come across the link, I will put it up.

The short holes have a bolt (plug) in them and if you want to use the short hole you just take the bolt out and put it in the long hole. I might have to call Berk in the morning. (I want to make sure I dont hurt my baby!!!)

The tall bungs imitate what we call "nonfoulers." The taller bung takes the sensor away from the exhaust stream, thereby reducing the risk of triggering a CEL.

+1 Long Bung... The others can be used for Secondary Wide band O2.

Yup, I spoke with Berk on the phone and they said the same thing. They are on the Z now and they help the Borla TD sound very sweet!!
