About this part

Product Details

This FMF Racing Factory 4.1 RCT exhaust system starts with a proprietary blend of aerospace-grade titanium, ensuring it's both strong and lightweight. It's designed specifically for the 2024 Kawasaki KX450F, incorporating FMF's latest Resonance Chamber Technology (RCT) both inside and outside the muffler. This advanced design helps to improve power delivery across the entire RPM range, giving you more grunt when you need it.

The muffler itself is finished with a striking blue anodized titanium body and capped off with a carbon fiber end cap, giving it a factory race look. A key design element is its shorter overall length, which not only looks good but also makes it less prone to damage in a crash. This design also works with FMF's Factory Forward Engineering, tucking the muffler closer to the bike's center of mass. This centralization of weight can lead to improved handling and a more nimble feel on the track. The system also includes a stainless steel Mid-Body Header for a complete package.

This system is manufactured entirely at FMF's Southern California facility, meeting their strict quality standards. The Rapid Tuning System (RTS) allows for adjustments to fine-tune performance. If you're looking to get the most out of your 2024 KX450F, this exhaust system is built to deliver significant power improvements and a race-ready aesthetic.
