I'm fixing to change my 02 sensors and ill be installing long tubes soon also is there a different sensor I should get? I always use the corvette rear 02s in the fbodys when installing long tubes. Do the trucks need extensions after installing long tubes? I'm guessing the rear 02s can be deleted on the trucks also.

New denso/delco stock sensors are all that should be needed for the fronts.

As for the rear, yes you can delete them but leave them plugged in and just zip tie them to the frame. Turn the codes off in the tune and be done. You want to leave them plugged in to stop the computer from doing cat tests at random, it's a feature you can not turn off in the 99-07 computers. It will do the test once and not again if they are left plugged in.
