FMF Factory 4.1 RCT Exhaust System

Sold by CG ATV & UTV Parts Shop — authorized distributor of FMF powersports parts in the USA.

Product Overview

FMF Factory 4.1 RCT Exhaust System

FMF Factory 4.1 RCT Full System

If you are looking to drop weight, improve looks and most importantly improve your bikes power band then look no further. The FMF Factory 4.1 RCT full system is constructed from aerospace-grade materials that meet FMF’s exacting specifications and is 100% manufactured in their Southern California factory. The patented MegaBomb header design allows exhaust gases to expand, cool and ramp back up at a higher velocity. This results in torque gains typically associated with longer headers, and the healthy over-rev of a short header. The muffler itself is shorter than OEM mufflers, making it less susceptible to crash damage and complements the centralized mass design by moving it closer to the motor. The rear end cap was engineered for fast and easy tuning by utilizing a retaining ring to keep the standard and optional inserts in place.

Features:

  • Massive power gains throughout the RPM range
  • Huge weight savings over stock exhaust
  • RTS (Rapid Tuning System) for quick and easy track-side tuning
  • Removable spark arrestor included
  • Meets AMA and FIM sound requirements
  • 100% made in the USA

Installation & Use

Installation complexity varies by application. For most bolt-on components, a basic socket set, torque wrench, and the vehicle’s service manual are sufficient. If you need detailed torque specs or wiring diagrams, refer to the manufacturer’s documentation or consult an authorized service center.

OEM-replacement parts should be installed following factory service intervals. Aftermarket performance parts may require additional setup, such as tuning or calibration — always verify compatibility before installation.
