HD-FXDF-III-X5.07 Utah III slip-on mufflers. Euro 4. Matte black

For a full blacked-out appearance on your 2017 FXDF Fat Bob 103, these Miller Utah III slip-on mufflers are finished in heat-resistant matte black stainless steel with matching standard style matte black billet aluminum end caps. These 85mm mufflers carry Euro 4 EC-BE approval, making them street legal throughout the EU while delivering a powerful Harley-Davidson sound. You can expect a performance increase of 2-3 horsepower and 3-4 Nm of torque without an ECU remap. Sold as a set, the kit includes a catalytic converter, removable dB killers, and all mounting hardware. They slip directly onto the stock head pipes, providing a hassle-free installation and a major upgrade in both style and performance.
