HD-SS-107-X39-X48.00 Destiny slip-on mufflers. Euro 5. Polished

The Miller Destiny slip-on muffler set is a premium upgrade for the 2021 Softail Slim 107, designed to meet strict Euro 5 standards. Sold as a set, these 85mm polished stainless steel mufflers feature standard style polished billet aluminum end caps. They provide a significant improvement in sound, delivering a deep Harley-Davidson rumble while remaining fully street legal. You can expect a performance increase of approximately 2-3 horsepower and 3-4 Newton-meters of torque without needing to remap the ECU. The system includes integrated catalytic converters, O2 sensor installation holes, and spot-welded dB killers. Designed for a quick slip-on installation on stock head pipes, the kit comes complete with all mounting hardware and an EG/BE service card.
