Getting Headers installed where to with 2nd O2

I'm getting my headers installed and the installer called me and asked where the other 2 02 sensors go. After some searching on here I noticed that I probably need a universal 02 sensor simulator to avoid check engine codes. Is this correct. And would there be a problem to run my car without the other two sensors til I get this simulator or what are my other options.
Thanks.
btw they are hotshot being installed on my 03 3.5 auto.

If you still have a main cat you could install the 2 sensors after it and all would work fine but you would need to extend the wires and weld 2 bungs on.

The simulator will eliminate the requirement to relocate but you still have to have either the sensors connected and wired up somewhere under the hood or resistors to simulate the o2 heaters or you will still throw a code. I believe there are instructions around somewhere on how to do that.

I ordered O2 simulators to simplify the install. Can't wait until i get my CATTMAN GEN2's

I recently received my O2 simulator after installing Hotshot headers and Cattman catback exhaust. I have been running the car without the two rear O2 sensors connected for about a month. The only problem that I have noticed is the CEL light.
