FMF Factory Fatty Pipe 025222 — GasGas / KTM / Husqvarna 85cc 2018-2024

Product Description

The FMF Factory Fatty Pipe is the ultimate choice for riders who demand professional-level performance from their 85cc machine. Inspired by the classic "works" cone pipes used by factory race teams, this exhaust is designed to optimize your engine's power delivery, providing a noticeable boost in torque and responsiveness right when you need it.

By effectively broadening and smoothing the power curve, the Factory Fatty ensures you have power across the entire RPM range. You will feel an increase in low-end grunt, a stronger mid-range pull, and improved over-rev for those long straightaways. Built from premium 20-gauge steel for the body and 19-gauge steel for the header, this pipe is as durable as it is high-performing.

Frequently Asked Questions

Q: Does this pipe work with a standard silencer?
A: Yes, it is designed to fit with the stock silencer, but we highly recommend matching it with an FMF Powercore or Shorty silencer to fully realize the power gains the pipe provides.

Q: Will I need to jet my bike differently?
A: Exhaust upgrades change the backpressure and airflow characteristics of your engine. We strongly recommend checking your jetting to ensure the bike is running correctly and to prevent engine damage from running too lean.

Expert Pro-Tip: When installing your new FMF exhaust, take a few minutes to check your exhaust O-rings at the cylinder flange. If they are flattened or brittle, replace them immediately. A fresh seal is critical to maintaining the exhaust scavenging effect that makes these FMF pipes perform so well.
