What is the benefit of the shorter muffler design?

The shorter muffler is less likely to be damaged in a crash. It also helps centralize the bike's mass by moving the muffler closer to the motor, which can improve handling and balance.

What materials is this exhaust system made from?

The system is constructed from aerospace-grade titanium, including the header pipe and muffler. The muffler also features a carbon fiber end cap.

Does this system come with everything needed for installation?

Yes, this is a complete system that includes the TI MB header and the muffler. It is designed to be a direct replacement for your stock exhaust.

Product Details

FMF Racing is well-known for making high-performance exhaust systems for off-road motorcycles. This Factory 4.1 RCT complete system is built specifically for your 2021-2023 Honda CRF450R or CRF450RX, designed to unlock more power and improve how the bike handles.

This system uses FMF's latest Resonance Chamber Technology, both inside and outside the muffler, to help boost power across the entire RPM range. They've also made the muffler shorter, which not only helps it survive crashes better but also moves the weight closer to the bike's center of mass. This is part of their Factory Forward Engineering, making the bike feel more balanced and easier to control. The whole system is constructed from aerospace-grade titanium, meeting FMF's strict standards, and it's all put together at their factory in Southern California.

You'll notice a significant increase in power with this exhaust. It also features a blue anodized titanium muffler with a carbon fiber end cap for a sharp look. The Rapid Tuning System (RTS) allows for quick adjustments if needed. This is a complete system, including the TI MB header, so you get everything you need to upgrade your bike's performance and handling.
