This is for all you guys that have used the MIL when eliminating the rear set of 02 sensors.
What did you do with the 02 sensor after cutting out the second set of cats? Do you just leave it hanging? Does the 02 sensor need to still be there?
Thanx

 

I cut all 4 cats, left both rear O2 sensors right were they are and fabricated some stainless steel tubing to replace the cats, it was a tight squeez, but once it was welded it was perfect, then stuck the MILs in the rear O2 sensors. I run a dumped Flowmaster 40 original, sounds wicked mean.

 

Hey thanx for the re-ply.
I am going to do that soon, I was looking at the MIL eliminators on line and they pretty easy to hook up. You just plug them in or solder the cheaper ones.
Do I need to get all 4 or just for the rear?

 

Na, you only need a set of two for the rears, the two front you leave alone. Mine are the plug in ones, i got from CRMotorsports.com i think it was. They're called Plug-n-Play.
