I am installing off road Long tube headers on my 2015 M6, asking if the 02 sensor front extensions are needed ?

I imagine it depends on which headers and their O2 positions. Some require extensions, some do not. Which headers are you installing? If your factory connections reach, there is no need for extensions.

Long tube headers need them.

Update, the front extensions are needed for sure with the rear being turned off with my tune. No way stock wiring harness could reach even after removing them from there mounting points.
