Description
If you’re running a Harley-Davidson touring rig, exhaust noise and performance are two sides of the same coin—and the S&S Cycle 4.5″ Mufflers deliver both without compromise. These purpose-built touring mufflers combine decades of S&S engineering with a dual-chamber design that produces a signature deep rumble while unlocking measurable gains in horsepower and torque. The styled aluminum endcaps give your bike a custom appearance that matches the performance upgrade under the bodywork.
Built entirely in the USA, these mufflers use a stainless steel baffle paired with RaceTEX cartridge packing for durability and consistent sound quality over thousands of miles. The removable dB reducer gives you flexibility—run quiet for long highway stretches or remove it for full acoustic presence when conditions allow.
