Show original supplier description
The Cobra 6047B Neighbor Hater Series mufflers are engineered to provide a deep, aggressive exhaust tone for Harley-Davidson Softail motorcycles equipped with the Milwaukee Eight engine platform, model years 2018 through 2026. Internally, they employ two-inch constant velocity cores for exceptional sound output and performance gains. The cores are further enhanced with bonded e-glass and stainless-steel mesh, contributing to a balanced sound quality, durability, and optimal engine performance. However, it is important to note that the original muffler inlet gaskets cannot be reused and will require replacement with new gaskets (DK P/N 267533) prior to installation. Additionally, due to emissions regulations, these parts cannot be shipped to California. These mufflers are specifically tuned for the Milwaukee Eight engine, ensuring they maintain necessary backpressure for optimal performance. The package includes two black steel muffler assemblies, four 1/4"-20 x 3/4" hex flange bolts, and installation instructions.
