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

If you want your Kawasaki to sound, feel, and perform like a true factory race bike, the FMF Factory 4.1 RCT Titanium Slip-On is the move. Designed with FMF’s latest Resonance Chamber Technology™ inside and out, this system smooths out the exhaust flow for serious power gains without breaking sound limits. The shortened design tucks closer to the motor for centralized mass, better handling, and less chance of crash damage — exactly what you want when pushing hard on track or trail.

The titanium construction keeps things ultra-light while maintaining durability, and the canister’s unique shape boosts internal volume to absorb more sound without choking performance. Add in FMF’s removable spark arrestor and you’ve got a slip-on that’s legal for the woods but still rips on the track. It’s race-proven design made practical for everyday riders.

Why We Like It:
It gives your Kawasaki that crisp factory bark and stronger midrange pull without being obnoxious. The throttle feels cleaner, power delivery smoother, and the bike just feels lighter and freer. It’s one of those upgrades you notice immediately, both in how it sounds and how it rides.

Why It’ll Work for You:
This slip-on helps your bike breathe easier and hit harder across the entire rev range. You’ll feel better low-end drive out of corners, a stronger mid-punch for jumps or acceleration, and a more linear throttle response that’s easier to control. The lightweight titanium body keeps weight low, the Resonance Chamber tames noise, and the removable spark arrestor means you’re ready for track days or trail rides. It’s plug-and-play performance built to last.
