HD-FB-E4-X12.10 Independence slip-on mufflers. Euro 4. Matte black

For the 2018 to 2020 Fat Bob 107 and 114, these Miller Independence slip-on mufflers combine German engineering with classic styling. This set features 85mm stainless steel bodies finished in a durable matte black, accented by polished aluminum Tapered style end caps. They are fully Euro 4 compliant and EC type-approved, meaning they are street legal across the EU while still delivering a rich, authentic V-twin soundtrack. The installation is straightforward as they are compatible with the original head pipes and include all required hardware. Each muffler contains an integrated catalytic converter and a removable dB killer, offering a perfect balance of performance, compliance, and that signature Harley-Davidson character.
