HD-FXDWG-III-X5.09 Utah III slip-on mufflers. Euro 4. Matte black

The Miller Utah III slip-on muffler set is a premium upgrade for the 2017 Twin Cam Dyna Wide Glide with the 103-inch engine. These German-made, matte black stainless steel pipes feature 85mm diameter cans and are finished with slash-cut matte black billet aluminum end caps. They are fully Euro 4 compliant and street legal across the EU, including an internal catalytic converter to maintain emissions standards without losing that deep Harley-Davidson rumble. You can expect a performance increase of around 2-3 horsepower and 3-4 Nm of torque without needing to remap your ECU. They are designed for a quick installation onto your stock head pipes and come with all necessary hardware. The dB killers are removable for maintenance. For Swiss riders, the required CH certificate is available separately under part number 719965.
