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 emit. Not to worry, S&S have 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. Wait, you only want one eagle and a few flags? Not a problem, they include a removable dB reducer that lets you tune the sound to suit your version of the American dream. Made in America, the GNX features their new durable Guardian Black finish and is relieved for shocks up to 13.5”.
