For my '14 Softail 103, does this exhaust have 18 o2? I plan to upgrade to Thundermax ECM

Bassani's pretty cool in this regard. They use 18mm O2 sensor bungs on their exhausts for your bike, but include adapters for the 12mm bungs as well. So, when you make the switch to the new tuner (which is an awesome one, by the way), you'll be all set.
