FMF Racing Kawasaki KX450F 09-11 SS Aluminum Factory 4.1 RCT SO Muffler w/ R. Carbon Cap

This FMF Racing Factory 4.1 RCT SO Muffler is built specifically for your 2009-2011 Kawasaki KX450F. It's designed to give you a significant boost in power across the entire RPM range, making your bike more responsive and capable off-road. The muffler itself is constructed from aerospace-grade materials, ensuring it can handle the rigors of riding while keeping weight down.

What sets this muffler apart is FMF's latest Resonance Chamber Technology, applied both inside and outside the unit. This advanced design helps manage exhaust pulses for improved performance. You'll also notice the shorter overall length, which not only looks good but also makes the muffler less likely to get damaged in a crash. Plus, FMF's Factory Forward Engineering moves the muffler closer to the bike's center of mass, which helps with handling and balance.

The muffler features a blue anodized titanium body and a distinctive carbon fiber end cap, giving your KX450F a sharp, race-ready look. It also includes FMF's Rapid Tuning System (RTS), allowing for easier tuning adjustments. This muffler is manufactured entirely at FMF's Southern California factory, ensuring strict quality control throughout the production process.
