FMF - Factory 4.1 RCT Titanium Slip-On Exhaust w/Mid Pipe (Honda)

FMF – Factory 4.1 RCT Slip-On Exhaust with Mid Pipe (Honda)

The FMF Factory 4.1 RCT Slip-On Exhaust brings championship-level performance and craftsmanship to your Honda. Designed and hand-built in FMF’s Southern California factory, this system uses Resonance Chamber Technology™ (RCT) both internally and externally to smooth out exhaust flow, enhance throttle response, and deliver stronger power through the entire rpm range. It’s the same technology trusted by FMF’s top race teams, fine-tuned for real riders.

The 4.1 RCT features Factory Forward Engineering, which positions the muffler closer to the motor for improved handling and mass centralization. Its shorter overall length reduces the chance of crash damage, while the aerospace-grade titanium construction cuts weight and boosts strength. Finished in blue anodized titanium with a matching titanium end cap, it delivers a true factory look. The Rapid Tuning System (RTS) makes insert and maintenance changes quick and easy, and a USFS-approved spark arrestor screen is included for trail legality.

Why We Like It:
It’s a factory-level slip-on that feels and sounds like a full system. The titanium build, deep FMF tone, and instant throttle response make it a serious upgrade that looks just as good as it performs.

Why It’ll Work for You:
This slip-on improves your Honda’s power and throttle feel without the complexity of a full system. It’s lighter, smoother, and easier to maintain, giving you race-ready performance that still fits your everyday riding. The included spark arrestor means you’re covered for both track and trail.
