Made of high quality stainless steel, the optional HDPA-D fitting allows you to remove the standard pre-silencer while preserving the catalytic converter, for a weight saving of 2.8 kgs (in combination with SPS CARBON TITANIUM) compared to the standard equipment. The assembly requires the use of the original heat shield cover. Perfectly compatible with the original silencer and the dedicated SPS CARBON line, it offers a deeper sound experience, perfectly in line with the Harley-Davidson concept. Installation is plug-and-play and no ECU mapping is required. The product has been developed based on the specifications of European models and does not fit models with non-EU specifications. THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR USE ON ROAD OR HIGHWAYS. CATALOGUE DOWNLOAD CATALOG
