i installed a BBK off road Xpipe. I bought a set of eliminators but they aren’t long enough to reach the rear o2s on the Xpipe. Should I get o2 extenders? Does it make a difference if I use em or not?

Depends on what the CEL is for. More than likely its the rear O2's, but best to scan it. I had an EGR code keep popping up when I did headers before.

You'll either need the eliminators or have the sensors turned off in the tune.

The rear O2 sensors technically monitor whether or not the cats are effective. They are not part of a wideband or closed loop system on this year model car. You can run with the CEL on, but it is better to have MIL eliminators in case there is a problem that you need to be aware of.

The lack of rear O2 sensors will not cause any form of performance issues. They are to check emissions only.
