How does the post lambda sensor come away from the frame
I’m trying to remove the header but can’t get the rear sensor unplugged to fit the Akra headers

There is a plug behind the frame spar, unplug it and the sensor comes off with the exhaust. It's pretty much next to/behind the control unit for the exhaust flap. PITA to get to.

Yes it’s under battery box
Can’t unplug it so was trying to get it off the frame to make it easier to unplug
Can’t remember it been as hard as this on my 2019 model
