Description

Experience unparalleled performance and sound with the FMF Factory 4.1 RCT Slip-On Muffler, a top-tier motorcycle exhaust system designed to optimize your Suzuki DR-Z400S. Featuring FMF's innovative Resonance Chamber Technology (RCT), this performance muffler utilizes a patented core shape and internal ducts to lower decibels without compromising maximum power output. The increased internal volume from the RCT system's chambers ensures improved exhaust flow, resulting in measurable power gains across the entire RPM range. Built with FMF's Factory Forward Engineering, the muffler centralizes mass, enhancing handling and reducing susceptibility to crash damage. The innovative rear end cap is designed for convenience, allowing simple installation of tuning tip inserts or the included spark arrestor with just four screws. This titanium slip-on is compatible with both your stock header or an FMF header, offering versatile installation. Each FMF Factory 4.1 RCT Slip-On Muffler comes complete with a QuietCore 94 dB insert and an integrated spark arrestor muffler, meeting AMA and FIM sound requirements (though it will not pass 2025 FIM sound regulations).
