HD-FBY-X39-X48.03 Destiny slip-on mufflers. Euro 5. Polished

For the 2021 to 2024 Fat Boy 114, these Miller Destiny slip-on mufflers provide a striking contrast with polished stainless steel bodies and matte black Slash Cut billet aluminum end caps. These 85mm mufflers are engineered in Germany to meet Euro 5 standards, making them fully street legal across the EU. Beyond the improved exhaust note, you can expect a performance bump of about 2 to 3 horsepower without needing to modify your ECU. The set includes a catalytic converter, O2 sensor holes, and all the hardware needed to mount them directly to your stock head pipes. With the dB killer spot-welded for compliance, these mufflers offer a high-quality, legal performance upgrade for your Softail.
