I have no clue why V/H insists on telling everyone the fitment won't be done til March due to o2 orientation issues?
Had a friend that had problems with o2, it wasn't the size, his are 12mm, it was the the placement. His sensors hit the jugs when putting pipes back on
I am thinking that was some other problem. The location of the o2 sensors on the Breakout headers are exactly the same as every other 2013 Softail. i know this because I compared the Slim, Fatboy, and the Blackline.
My O2's popped into the BR 2-2 headers in the exact same location as stock.
Another point I want to mention is that V/H is telling folks they are concerned with the current part number for the 2-2 being too close to the oil lines. In reality, the stock exhaust is extremely close to all 3 oil lines, and the 2-2 is moved about 1.5" AWAY from the oil lines.
The people manning the V/H phones just have no clue what they are talking about. You would not believe the BS I have been told from these people on 4 different occassions. Pitiful......
