791131 Flfb Fat Boy Flstfi Fat Boy Grey Ghost Euro 5 2025 to Presen

This MCJ Royal 100 system is a premium 2-into-2 exhaust designed specifically for Softail Fat Boy models from 2025 to present. As an E-approved system, it comes complete with headers, heat shields, and mufflers, but the real standout feature is the adjustable exhaust valve. This allows you to manually tune your bike's bark to your preference while remaining legal when necessary. The kit includes a manual adjusting lever that can be mounted on the handlebars or tucked below the tank for a cleaner look. Note that the Royal Style 100mm end caps are sold separately, allowing you to customise the final aesthetic. It is a fantastic choice for riders who want performance and sound control without sacrificing compliance.
