Frequently Asked Questions

Will these fit my 2018+ Fat Boy or Dyna?

No — this part is specific to 2007-2017 models. Milwaukee-Eight Fat Boys and Dynas (2018+) require different slip-ons.

Do I need a tuner with these slip-ons?

Slip-ons alone typically do not require remapping, but a fuel/air recalibration may improve performance depending on other modifications.

Are they street legal?

Check your state and local noise ordinances — muffler regulations vary by jurisdiction.
