Truth or urban legend ?

I read that on the internet so.............?????

I know a lot of guys say crosstalk is BS but I still find my self worried about it. I will call FM tomorrow and find out for sure. I trust them to tell the truth.
I will up-date.

Yes, the sensors in the head-pipe are 12 MM on the 10 & up, but that has nothing to do with really much else.

The 09's are preferred by many including F/M and are 18 MM.
If you use an auto tune unit like on a PC or a PV, they do not work with 12 MM.

I couldn't explain cross-talk if my life depended on it. But, I can say that I'm running a completely stock intake and exhaust EXCEPT for a de-catted stock headpipe. The bike runs great. No pinging, cooler on the right side for rider and passenger, and an average of 42 MPG.
