FMF Factory 4.1 RCT Slip-On Exhaust Honda CRF450R
If you are looking to drop weight, improve looks and most importantly improve your bikes power band then look no further. The FMF Factory 4.1 RCT Slip-On muffler was designed to bring out the hidden power potential in your machine by improving top-end pull and low-end torque. All 4.1 RCT mufflers are manufactured in FMF's Southern California factory using aerospace-grade materials that meet FMF's exacting specifications. A patented core shape enhances exhaust pressure for optimal power output while also lowering the sound level. The muffler itself is shorter than OEM mufflers, making it less susceptible to crash damage and complements the centralized mass design by moving it closer to the motor. The rear end cap was engineered for fast and easy tuning by utilizing a snap ring feature to keep the standard and optional inserts in place.
- Massive power gains throughout the RPM range
- Huge weight savings over stock exhaust
- RTS (Rapid Tuning System) for quick and easy trackside tuning
- Removable spark arrestor included
- Quiet insert included (94db)
- Can be used with FMF or stock OEM Header
- 100% made in the USA
