2010 headpipe on a 2009 EG?
I have a set of fullsac headpipes for 2010-up models. My bike is a 2009 EG. I know the 2010 pipes use 12mm o2 sensors farther from the engine, my 2009 EG uses 18mm sensors. Can I install 12mm sensors and extended wires on mi bike with the 2010 headpipes?

Shouldn't be a problem. I have a Samson Caliber pipe for an '09 and it's on my '12 Ultra. With the appropriate O2 sensor wire extensions.
You shouldn't need any wire extensions since your O2 sensors will now be closer to the point where they connect to the rest of the wiring harness. (Inside the right-side cover).

To use the 2010 pipes on your '09, just weld the correct bungs in the proper place and plug the unused ones.
That is what the after market pipe manufactures do when selling pipes that are rated for used on multiple years. They just include plug and say to use them in the unused holes.

The location of the O2s in the 09 headers are in a more suitable place to properly sample exhaust gases, in my opinion, as compared to the location of the sensors in the 2010 and above model years. Plus they are wide band sensors and the 12mm sensors are narrow band. I cannot remember the bandwidth of each. As for whether or not the 18mm is heated on the OEM set-up...well I don't know.
But what I do know is that the 18mm Bosch wide band sensors I use associated with my Revolution Performance EMS are heated and they plug directly into the O2 socket connectors under the right side panel with no modifications or resultant problems.

If I had known then, what I now know about O2 sensors, I would have just blocked them off completely and shut down their inputs to the ECM.
Their function is purely Emissions related in stock form. The O2 sensor is more like a switch instead of a sensor. All it does is sniff the exhaust for the residual oxygen level and tell the ECM if the O2 is above or below the manufacturers preprogrammed level.
Based on that info the ECM either adds fuel or takes away fuel in an attempt to get back to emission standards.
The ECM ignores the O2 input during almost all situations except steady throttle conditions with little or no load. I can give you more info if you are interested but won't bore you with it unless you really want me to.

I don't use mine. Plugged up off.
Use the PC-V and the bike has been dyno-ed, so I don't really have a need for them at this point with the tuner that I have.
Better yet, sell your 2010 pipe on this site in the classifieds and get the pipe for the 09.
Do you still have your 09 stock head-pipe?
I know someone who may want it if you want to sell it too.
PM me if so.

buggin02,
I rather keep the O2 sensors since I have the Power Vision and it uses the factory sensors for the "Basic" Autotune. If I had a power commander, I wouldn't have this problem. Thanks for the info though.
