Upgrade the exhaust style and sound of your Harley-Davidson with the COBRA 6520 909 Twins 4-Inch Chrome Slip-On Mufflers. Designed for the 2018–2021 Harley-Davidson FLSB Softail Sport Glide, these slip-ons provide a clean, stealth-inspired appearance while delivering the traditional Harley sound riders expect. The mufflers are engineered for a direct-fit installation on the original exhaust system, making them a practical choice for riders seeking enhanced styling and performance without replacing the complete exhaust system.
Each muffler features a downward-angled 4-inch outlet that creates a streamlined profile on the motorcycle. COBRA’s distinctive Twin Tip design combines a scalloped, smoothly rolled outer tip with a matching scalloped inner tip. This refined construction delivers an elegant finished appearance without visible external screws. Inside, a 2.25-inch perforated core helps produce the recognizable Harley-Davidson exhaust note while supporting consistent exhaust flow.
Finished in show-quality chrome, the COBRA 6520 mufflers complement the factory styling of the Softail Sport Glide and are built for long-term use. They are 50-state legal and backed by a limited lifetime warranty. Manufactured in the USA, these mufflers are an exact fit for 2018, 2019, 2020, and 2021 Harley-Davidson FLSB Softail Sport Glide models. Verify the motorcycle model and year before ordering to ensure proper fitment.
