HD-FBY-X39-X48.10 Destiny slip-on mufflers. Euro 5. Matte black

These Miller Destiny slip-on mufflers are a top-tier choice for the 2021 to 2024 Milwaukee-Eight Softail Fat Boy 114. Finished in a heat-resistant matte black, this stainless steel muffler set features 85mm diameter bodies and polished billet aluminum end caps in a tapered style. They are fully Euro 5 compliant and street legal across the EU, coming complete with a catalytic converter and an EG/BE service card. You can expect a nice performance bump of around 2 to 3 horsepower and a significant improvement in that classic Harley rumble without needing an ECU remap. The kit includes all necessary installation hardware and features an O2 sensor install hole for a straightforward fit onto your stock head pipes. These German-made pipes even come with a spot-welded dB killer for a hassle-free, legal ride.
