Im having a BBK O/F H-pipe installed this weekend along with a set of MAC Long tube headers....I have a Diablo Programmer for my 1998 Mustang GT and I know i can just turn off the rear 02sensors then i dont get a check engine light. Now if I buy the BBK 02 Sensor extensions will that still trigger the check engine light because there are not cats? Also if i turn the rear sensors offwith the programmer there is no sense is buying the extensions....correct?

Thanks

 

You'll have to get a set of the extensions for the front sensors but just turn the rear ones off with the programer. Use the sensors to plug the holes and your good. The extensions for the front sensors is a must and will not throw a light.

 

Your question is a bit confusing...

But extentions won't eliminate a CEL, they only extend the wires so you can plug your harness back into the O2 sensor.

I don't know of anyone who's left the O2's plugged in, left the wires off & turned off the rear O2's with a programmer, if that's what your question really is.

 

I agree with dan. Try re-wording your question a little bit, because I just felt like a littlevirgin sitting next to jenna jameson.

 

sorry about the all the confusion guy now whats the best way to read my Air/Fuel ... I have a narrow band gauge is it worth hooking up or just going and getting a wideband kit.
