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.

 

Key Features:

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

  • Patented core shape lowers sound without sacrificing output

  • Patented canister design increases internal volume and durability

Unless you're trying to eat a whole meal in them, I suggest you buy.
Size: 12oz - 500 Count, Color: White
Good quality for the price you're paying. Some of the bowls crack a little easily, but they hold up pretty nicely overall. From hot soups to ice cream and cereal or a nice bowl of wet food for your pet. They're a good size for a serving and don't wilt quickly when holding any liquids. And they compost, so it's good wn the carbon footprint since I can use them instead of seeking out cardboard for my garden compost.

So many for so cheap.
Size: 12oz - 500 Count, Color: White
So apparently I’m not great at estimating what 12 ounces really looks like in a bowl. Therefore they were smaller than I was expecting, but since I’m lazy and hate to do dishes, they are perfect for our household. Too small is better than too large in my book , as we have no problem with going back for seconds, which these bowls will definitely hold up for. They are leak proof and a great value for how many you get. The thickness it about what you’d expect although the lip seems slightly thin and bends easily when trying to separate them, which isn’t difficult, but not simple by any means. Again not a deal breaker for our house.

Great product
Size: 12oz - 500 Count, Color: White
These bowls and plates are awesome! We love that they are compostable when we are home but we also use them camping and love that they don’t have the waxy coating so we can throw them in the solo stove and they burn clean. They are also strong and can easily hold a heavy amount of food.

I like these bowls. Perfect size for serving a crowd.
Size: 12oz - 500 Count, Color: White
This is an incredible value. Tons of bowls. They are very sturdy. I have to double them if I serve soup.
