o2 sensor question

[streetsteve]

I have a 04 gt pypes offroad x pipe, the wires for the 2nd set of o2 sensors dont reach, obviously I need extenders, can I just plug the holes in the pioe and not have the second set, I dont have a tuner yet but with my last car after I got a tune done for no cats they completely tune out the second set of sensors so I never had to put em back in, is this the same? Thanks for any and all input towards this subject,

maybe plug in the sensor and leave the other side unhooked so you can plug the hole. even cut the wires off maybe.

I may be reading this wrong, but if you are considering just leaving the holes open I would say definitely plug the holes if nothing else. You don't want an exhaust leak

yeah plug them. they are the same thread as a spark plug I believe

Plugging the hole and unplugging the sensor will both kick out a CEL, if you want to avoid that get the MIL eliminators. Or make your own...
