Description
Upgrade your M8’s exhaust note without committing to a full system overhaul. The S&S Cycle GNX slip-on delivers genuine V-Twin character through a louvered baffle design that produces a deeper, more aggressive tone—even when paired with stock headpipes. This bolt-on muffler combines S&S Racing pedigree with measurable performance gains and a purpose-built finish that demands attention.
Engineered for riders who want authentic sound and power without compromise, the GNX arrives SAE J2825 compliant and includes a dB reducer for jurisdictions that enforce noise regulations. Installation is straightforward, and the Tuxedo Black end cap echoes true racing heritage on your machine.
