Note for 2021+ Softail:
These slip-on mufflers have a single O2 sensor port, while Euro 5 Softail models have two. To prevent trouble codes, deactivate the second sensor using tuning software like Vance & Hines FP4 or Dynojet Power Vision. Use part C852-744444 to plug the sensor connection.

Note for 2017+ models: 2017+ Harley models may need replacement muffler gaskets if already equipped. Find replacement gaskets here.
