The Intruder Exhaust CO2 sensor & year thread

UK/EU Bikes
The CO2 sensors are only on a fuel injected bike, not any of our carbed

M800
2005+ 1 sensor / 2009+ 2 sensors
C800
2006+ 1 sensor / 2007+ 2 Sensors

If an owner of a bike with CO2 sensor/s is considering buying an exhaust with no CO2 sensors holes/bosses, what is the way to go?
I believe it is simply to have the connecting boss or bosses fitted depending on year of bike or disable the CO2 sensors by either cutting wire 32 at the ECU to switch that facility off or unplug the sensor and fit either 1 or 2 CO2 sensor eliminators instead, which one depending on the model and year

If an owner of a bike with no CO2 sensor/s is considering buying an exhaust with CO2 sensors holes/bosses in the exhaust, what is the way to go?
I believe it is simply to have the connecting boss or bosses fitted with a hole blanking plug or screw in a bolt that will close off the small C02 sensor fitting holes

The 2013 and possibly others years from 2011+  have the wire 32 at the ECU blanked off so I presume the only current way known of disabling the CO2 sensor is to fit 2 CO2 sensor eliminator plugs if removing the CO2 sensors

Can someone confirm this is all true or add any further info that could be useful
This post will then be updated with useful info to help people in future
