FMF Racing Factory 4.1 RCT Anodized Titanium S/O

What you get with this FMF Racing Factory 4.1 RCT exhaust is a complete muffler assembly designed to bolt right onto your 2021-2023 Honda CRF450R or CRF450RX. It features a blue anodized titanium body and a carbon fiber end cap, giving it a sharp look that matches its performance. This isn't just about looks, though; the design incorporates FMF's Resonance Chamber Technology, both inside and out, to help manage exhaust pulses and improve power delivery across the entire RPM range. The shorter overall length is a smart move, making it less likely to get damaged in a tip-over and also helping to centralize the bike's mass by allowing the muffler to be mounted closer to the engine. This improved mass centralization can make the bike feel more nimble and easier to handle.

FMF builds these mufflers entirely at their Southern California factory, using only aerospace-grade titanium alloys that meet their strict standards. This well-built construction ensures durability and performance. The Rapid Tuning System (RTS) is also built-in, which is FMF's way of saying this muffler is designed for easy tuning and optimal performance right out of the box. If you're looking to get the most out of your CRF450R or CRF450RX, this muffler is a solid option for noticeable power improvements and a more balanced feel.
