personally i do it one of 2 ways. I either unplug the sensors at the connector and then transfer them once i have the Stock-H pipe onto the new H-pipe in the same location they go... or since i already know which ones go where just remove them while the mid pipe is still on the car
I disconnected the sensors at the connector & transferred them to the prochamber off the car, but let me tell you, if you do it that way be prepared to cuss a lot trying to reconnect the upstream sensors. The plug is between the engine & the firewall; I had a hell of a time trying to reconnect them. Probably the worst part of the entire install besides the passenger header bolts.
