Upgrade the exhaust presence of your compatible M8 FL motorcycle with S&S Cycle GNX Slip-On Mufflers, Part Number 550-0991. Built with S&S racing heritage styling, these mufflers deliver a premium combination of fit, finish, sound, and power while maintaining a clean appearance with chrome muffler bodies and black tuxedo-finish end caps. The slip-on design provides a practical way to enhance the motorcycle’s exhaust system without replacing the complete exhaust assembly.
The GNX mufflers are engineered for riders who want a purposeful exhaust tone and refined installation. Each muffler body features a full 4-1/2-inch outside diameter for a substantial appearance that complements the motorcycle’s overall design.

Muffilers are relieved to accommodate shocks up to 13-1/2 inches in length, supporting compatibility with specified motorcycle configurations.
Sound control is built into the design. With the included dB reducer installed, the mufflers comply with SAE J2825 sound-level requirements, helping provide a performance-oriented exhaust note within the stated standard. The mufflers are supplied as a matched pair for a complete left-and-right installation and are made in the USA.
