On my old exhaust setup I added a bung at the end of the downpipe for the air fuel sensor and plugged the rear o2 into the test pipe.

On the new setup the downpipe has NO bung, the test pipe has an o2 bung and there is a bung at the begining of the hks cat back.

My question is can the sensors be moved down the line? Air fuel sensor in the test pipe and rear o2 in the cat back?

 

That should be fine I don't see why there would be any problems with moving them down.
