Product Description

Unlock the true potential of your engine with the FMF Factory 4.1 RCT Slip-On Muffler. Engineered for riders who demand championship-level performance, the Factory 4.1 RCT features FMF's patented Resonance Chamber Technology. This innovative core shape effectively lowers decibels while ensuring maximum power output, giving you the best of both worlds on the track or trail.

The system is built using FMF’s Factory Forward Engineering, which centralizes mass to improve bike handling and makes the unit less prone to crash damage. With a durable blue anodized titanium body and a lightweight carbon fiber end cap, this muffler not only performs at a high level but also offers a professional, factory-ready look for your Honda CRF250R. It is compatible with your stock header or can be paired with an FMF header for even greater gains.

Frequently Asked Questions

Q: Does this muffler come with a spark arrestor?
A: Yes, it includes both the spark arrestor and the QuietCore 94 dB insert, making it compliant for various riding environments.

Q: Can I use this with my stock header pipe?
A: Absolutely. The Factory 4.1 RCT is designed to be compatible with both the stock OEM header and FMF performance headers.

Expert Pro-Tip: When installing a slip-on, always use a high-temp silicone sealant on the slip-joint connection. It prevents exhaust leaks, which can cause erratic idling or decel popping, and it stops grit from working its way into the junction.
