FMF Factory 4.1 RCT Exhaust System Husqvarna FE250 2020

FMF Factory 4.1 RCT Exhaust System Husqvarna FE250

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.
