{"product_id":"4-5-inch-mufflers","title":"4.5-Inch Mufflers","description":"Dialed in to enhance the performance of the Milwaukee-Eight® engine, these Screamin' Eagle Street Cannon Slip-On Mufflers feature a large inlet for improved airflow. When teamed with a free-flowing air cleaner, these mufflers deliver horsepower and torque gains you can feel. The large 4.5-inch diameter mufflers are tuned to provide a rich exhaust note, a deep bass rumble, and a great throaty sound when you roll on the throttle. To strike a balance with your neighbors, the large internal volume and strategically designed baffles help maintain the peace at partial throttle. The large diameter body adds a muscular look to your ride, and the newly designed mounts keep the mufflers tucked in close to the bags for a clean profile. They feature a die-cast Screamin’ Eagle® medallion on their flanks and can be fitted with a variety of styled muffler end caps for a custom look.\n\nThese mufflers are made of steel and are sold as a pair. Installation requires the separate purchase of Muffler Clamps P\/N 65900012 and 65900015. Crucially, all models require ECM calibration with a Screamin’ Eagle® Pro Street Tuner or a dealership-installed Screamin’ Eagle calibration for proper installation.\n\nFitment includes '17-'25 Touring models, with specific exclusions: does not fit '23-later Center-Cooled models, Trike models, or '21-later California models. Refer to H-D.com\/shop for the most current status regarding California compliance. They are 50-State U.S. EPA compliant.","brand":"Screaming Eagle","offers":[{"title":"Default Title","offer_id":52663621321016,"sku":"64900552A","price":549.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687676739.jpg?v=1784328516","url":"https:\/\/store.motormia.co\/products\/4-5-inch-mufflers","provider":"MOTORMIA","version":"1.0","type":"link"}
