Anyone know if the stock rear O2 sensors wiring will plug into the sensors when you install headers and the green catted H-pipe or do you need extensions (I know they dont work for the fronts).

Good to know! Thanks!
In case you do have an issue....I had O2 problems issues after AMR headers. I discovered the shop used extensions made in Taiwan!! I also stretched the harness to avoid extension but for some reason still had an 02 issue. Early 2017, another Mustang shop installed Raptor F150 O2's with long heavily insulated sealed harnesses. I've never had an issue since.
I've heard of some cases where an O2 restrictor is needed. Thats good to know since Im going to order new rear o2 sensors anyway.
You shouldn't need extensions for any of the O2's front or back when running long tube headers. The wiring harness can be adjusted to reach.
