S&S GNX Slip-On Exhaust


A low idle combined with a plugged up exhaust conspire to mute the true sounds of freedom that your machine was designed to roar. Not to worry, S&S created the GNX slip-on mufflers with one thing in mind - belting out the flag waving, eagle flying song of the American v-twin! Combining a 4-1/2 inch sleeve with a tuned baffle and race inspired tip, the GNX lets the sound and power flow.

  • Unique louvered baffle delivers a rowdier tone
  • Enough clearance for 13.5 inch long shocks
  • Removable dB reducer insert (J2825 compliant)
  • Sold in pairs
  • Made in the USA
