GNX mufflers

GNX Slip-On Mufflers for 2017-2020 M8 Touring models

Features and Benefits

The M8 engine is a powerhouse, but a low idle combined with a plugged up exhaust conspire to mute the true sounds of freedom that this machine was designed to roar. Not to worry, S&S created the GNX slip-ons with one thing in mind and that’s belting out the flag waving, eagle flying song of the American v-twin. Combining a 4.5” shell with a tuned baffle and race inspired tip, the GNX lets the sound and power flow out of the M8.
