Matte black ceramic coated. Individual crossover head pipes offer the traditional look and are best in giving the distinctive H-D potato-potato sound. 2 1/4″ 220° full coverage heat shields give this head pipe set a massive look and a long lasting finish. Special propriety bends in combination with stock 1 3/4″ diameter pipes provide the best possible horsepower and torque from your engine. Can be used with stock mufflers or add a pair of Vance & Hines slip-ons, of the correct model year, for maximum performance, torque and great sound. Note: An O2 sensor plug set must be separately ordered when required. Note: Performance slip-on mufflers are separately available.
