Co2 sensors unplugged!?

Sorry for the title saying Co2 i ment to put 02 iphone auto corrected it
I was looking over my bike I just bought about a month ago from a dealership 07 dyna. I noticed that the o2 sensors are unplugged. It has Vance and Hines big radius pipes on it.. Is it an issue that those aren't connected? ImageUploadedByMO Free1377819775.694050.jpgImageUploadedByMO Free1377819787.386919.jpg

Thought the o2 sensors were only relevant in a 2 to 1 exhaust since that allows for an air push/pull dynamic. My exhaust looks like a 2 to 2 but there is a cross over. The big radius don't even have that.

O2 sensors are used on all EFI bikes to allow the unit to adjust the mixture, regardless if it's 2-2 or 2-1. Yours may be unplugged because of an aftermarket fuel controller.

Thanks for the correction. I knew someone would chime in if I was wrong!
