4.0 Header o2 question

I did a quick search and couldn't find what I'm looking for..

I ordered a set of dt shortys for my '11 4.0, and am curious what to do with the o2 sensors located on the top of my stock manifolds; the headers have no bungs on them.. I am currently going back and forth with summit on trying to get the gaskets that they didnt include with them, but were they supposed to send something else for them? They seem to have no clue. Thanks guys

 

You will have to get bungs installed if you want to run the O2 sensors. Most exhaust shops can do it.

 

O2 simulator is needed

 

O2 sims only help with deleted Cats, the shorties headers still use your stock cats so you will have to have bungs installed for your O2 sensors. Your truck will run like shit without them.
