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.

  • Latest FMF Resonance Chamber Technology™ (RCT) for balanced flow and power

  • Patented core shape lowers sound without sacrificing output

Fits perfectly in the Epson ET-2720 and reset software worked!
The waste ink pad replacement fit perfectly in the Epson ET-2720 and looked to be identical to the original that needed replacing. The reset software they provide also worked without any issue.

Not everything included
It says it comes with program to reset the printer an all the information that came with the tanks takes you to sites that want you to buy the key to unlock. These were purchased with the idea everything you needed came with it.

Perfect to fix your Epson Ink Pad Counter Issue
Exactly what I needed! My Epson ET-4700 started displaying an 'E-11' error on the display so I learned I would have to replace the ink pad. The package came with 4 ink-pad receptacles, four baggies for discarding the old ones, plastic gloves and even a miniature screwdriver to get the backing off of the printer. The hardware part was super simple to remove the old and install the new. Hit a bit of a snag with the included software(which was a link to a website)which Windows Defender kept blocking no matter what I tried, but a quick email to support they answered right away. Sent me to a link for better software and I was able to successfully get my printer working again. A+++ transaction and service. Thanks again!
