HD-SP-S3-X2.06 Silverado III slip-on mufflers. Euro 4. Matte black

These Miller Silverado III slip-on mufflers are a premium choice for 2017 to 2020 Sportster owners looking for that unmistakable Harley-Davidson rumble while remaining street legal. Finished in a heat-resistant matte black, this stainless steel set features high-polished aluminum end caps in the Standard style. They are Euro 4 compliant and come with an EC type approval service card, including the necessary catalytic converter and removable dB killer for maintenance. You can expect a performance bump of around 2 to 3 horsepower and 3 to 4 Nm of torque without needing to remap the ECU. These are designed for a straightforward slip-on installation onto stock head pipes and are sold as a set. They fit XL883 and XL1200 models including the Iron, Custom, and Forty-Eight.
