Note for 2021+ Softail:
On 2021 and newer Softail models, Harley added extra O2 sensors on the original mufflers to meet Euro 5 standards. To prevent trouble codes, the additional sensors must be deactivated using tuning software like Vance & Hines FP4 or Dynojet Power Vision. Use part C852-744444 to plug the physical sensor connection. Local workshops and dealers may also be able to help you deactivate the sensors.
Note for 2017+ models: 2017+ Harley models may need replacement muffler gaskets if already equipped. Find replacement gaskets here.
