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; 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. Each muffler includes 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".

These would be great without the cat delete headers. At a steady cruising throttle they're tolerable.
Very quality product

These slip-ons are great! They make my Street Glide Special sound so much better. When you crank the throttle, they sound incredible. Thank you.

The mufflers look and sound as advertised. The muffler clamps have an Allen head bolt. The directions say nothing about needing a 6 mm Allen head socket. Should have not followed the directions and use the original Harley muffler clamps. As one of the Allen head bolts stripped out while trying to torque down to spec.
