Description S&S Cycle GNX 4.5 Slip-on Mufflers 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 4.5 slip-on mufflers with one thing in mind and that’s belting out the flag waving, eagle flying exhaust sound 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 the durable Guardian Black finish and is relieved for shocks up to 13.5″ – FEATURES: GNX 4.5 Slip-on Mufflers give your M8 a true V-Twin rumble without a full system 4.5″ slip-on with premium fit, finish, sound and power Unique louvered baffle delivers a rowdier tone, even with stock headpipes SAE J2825 Sound Level Compliant (with included dB reducer installed) S&S Racing heritage styled end cap in Tuxedo Black finish Made in USA! – NOTES: GNX 4.5 Slip-on Mufflers do not fit trike models – – FITMENTS: 2025 Harley-Davidson FLHXU Street Glide Ultra – – 2025 Harley-Davidson Electra Glide Police FLHTP – – 2025 Harley-Davidson Street Glide EFI FLHX – – 2022-2023 Harley-Davidson FLTRKSE CVO Road Glide Limited – – 2022-2023 Harley-Davidson FLHXST Street Glide ST – – 2022 Harley-Davidson FLTRXST Road Glide ST – – 2020-2024 Harley-Davidson FLTRK Road Glide Limited – – 2019-2022 Harley-Davidson FLHT Electra Glide Standard – – 2018-2022 Harley-Davidson FLTRXSE CVO Road Glide – – 2017-2025 Harley-Davidson FLHRXS Road King Special – – 2017-2025 Harley-Davidson FLHXSE CVO Street Glide – – 2017-2025 Harley-Davidson FLHX Street Glide – – 2017-2025 Harley-Davidson Electra Glide Police FLHTPI – – 2017-2024 Harley-Davidson FLHTK Ultra Limited – – 2017-2023 Harley-Davidson FLHXS Street Glide Special – – 2017-2022 Harley-Davidson FLTRX Road Glide – – 2017-2022 Harley-Davidson FLHR Road King – – 2017-2022 Harley-Davidson FLTRXS Road Glide Special – – 2017-2021 Harley-Davidson FLHTKSE CVO Limited – – 2017-2019 Harley-Davidson FLHTKL Ultra Limited Low – – 2017-2019 Harley-Davidson FLHTCU Electra Glide Ultra Classic – – 2017-2019 Harley-Davidson FLTRU Road Glide Ultra – – –
