Hey guys i just need a confirmation on something. If you eliminate 4 cats then you should need 4 MIL Eliminators right?

no, only 2 for the rear 2 o2 sensors. the front 2 are for A/F, you need those.

yes you do eliminate four cats but there is not an o2 sensor for each cat. As stated above the first set messures the a/f. the second set(the set behind all 4 cats) just makes sure the cats are fuctioning properly.

You only need the MIL eliminators for the rear 02 sensors. Dont mess with the front 2.

What they said. Just the two for the rear O2 sensors.
