Getting code P2270!

I have a 2007 Solstice GXP and recently installed a downpipe with no cat. I disabled the P0240 upon installation, I do not have the rear O2 sensor screwed into the exhaust pipe, I used a plug instead. I guess I will have to disable the P2270 too?!?

Thanks

Put it back in.

Either A. Disable it.

or B. Plug it back in.

However, to my knowledge, the 2nd o2 is basically a way to tell you if your cat is messed up.

Disable it using your editor software in the DTC's section. No dirty hands or burnt flesh. Problem solved.
