Question...with an offroad exhaust,would there be any gain in turning off rear o2 sensors. Predator allows you to do this,just wondered if it would help boost power?

Does the 05 even have rear O2 sensors? If memory serves (I was just under the car this past weekend), there are only 2 O2 sensors, each of them plugged right into the middle of each cat. I could be wrong though.

I would consider those rear...there are more O2 sensors ahead of the ones in the cats. I took them all out when I changed over to Bassani cats. On the driver side the first sensor is on the manifold itself and doesn't need to be removed. The first O2 sensor on the passenger side is located just after the manifold but before the stock cats.

I HAD to turn my rear o2's off to keep the CEL off. I have SCT though.

So if I was to replace my factory H-pipe with Bassani's full x-pipe with removable cats, there would be a good chance that my check engine light would come on?
I don't want to have to buy a tuner if I'm replacing the h-pipe.
