FMF – Factory 4.1 RCT Complete System (Kawasaki)

The FMF Factory 4.1 RCT Complete System brings championship-level performance, power, and precision engineering to your Kawasaki. Designed with FMF’s exclusive Resonance Chamber Technology™ (RCT) both inside and out, this system smooths exhaust pressure, boosts power across the rpm range, and cuts sound levels — all while delivering that crisp, unmistakable FMF tone.

FMF’s Factory Forward Engineering moves the muffler closer to the motor, centralizing mass for improved balance and handling. The shorter overall length helps prevent crash damage, while the patented canister shape increases internal volume, allowing more sound-absorbing material without restricting flow. Built entirely from aerospace-grade materials and handcrafted in Southern California, the Factory 4.1 RCT is made to perform, look, and sound like a true factory system.

Why We Like It:
It’s FMF’s top-shelf system for good reason — lighter, stronger, and noticeably more responsive. The titanium build and carbon end cap look straight off a race bike, and the sound is pure FMF: clean, deep, and aggressive without being obnoxious.

Why It’ll Work for You:
This system gives your Kawasaki more usable power and a smoother throttle feel from low rpm to wide open. The improved flow helps the engine breathe easier, while the mass-centralized design keeps the bike stable and responsive. Plus, the included 94dB insert lets you fine-tune sound for different tracks or trails.

Variants / Options:
Includes complete header, mid-pipe, and muffler assembly. Compatible with optional spark arrestor and tuning inserts.

Works Great!
Color: Black/Battery
I've only used it a few times since it arrived and it works great. Much better than the hand cranking can opener I've been using. It's a little loud, but that's not enough of a deterrent for me to stop using it. The noise is a temporary annoyance that I'll gladly put up with to have a can opener that actually completely opens a can.

Super convenient and easy to use!
Color: Black/Battery
This electric can opener is a game-changer in the kitchen. It operates smoothly with just the press of a button and leaves safe, smooth edges on the cans. Very compact and handy.

Injured finger from use
Color: Black/Battery
Just used the product for the first time today. Beware, it does work but it cut my daughter’s finger open really bad because it made the edge of the can stringy and she cut her finger on it. Be careful.
