FMF Racing KTM/Husqvarna Factory 4.1 RCT S/O Carbon

If you're looking to get the most out of your 2019-2021 KTM 250 SX-F or XC-F on the track or trail, this FMF Racing Factory 4.1 RCT muffler is a solid choice. It's built to enhance your bike's performance, giving you that extra edge when you need it most. This muffler is designed to work with your bike's existing exhaust system, making it a straightforward upgrade for riders focused on maximizing power and responsiveness.

FMF Racing incorporates their latest Resonance Chamber Technology (RCT) both inside and outside the muffler. This advanced design helps manage exhaust pulses for improved power delivery across the entire RPM range. The muffler itself is constructed from a high-quality, proprietary blend of titanium alloy, known for its strength and light weight. It features a distinctive blue anodized titanium body and a carbon fiber end cap, which not only looks sharp but also helps reduce overall weight. A notable design feature is its shorter overall length, which helps protect it from damage in the event of a crash and also allows for FMF's Factory Forward Engineering. This means the muffler is positioned closer to the motor, helping to centralize mass for better handling and bike control.

This muffler is manufactured entirely at FMF's Southern California facility, ensuring close attention to detail and quality control. While this muffler is designed to bolt on, always refer to the manufacturer's installation instructions for specific details and any recommended hardware or gaskets not included.
