This brand new muffler design is the result of the collaboration between KTM USA Motorsports and FMF.
FMF RCT: Resonance Chamber Technology A resonance chamber works like two rooms connected by an open doorway. If you were to slam the outside door on room number one, some of the sound and energy would be absorbed by that room, dampening those forces as they trave through the passage into room number two. This effet lowers decibels and increases the life of muffler packing. The chamber's internal ducts increase volume for improved exhaust flow, resulting in power gains throughout the entire range of power.
Highlights:
Patented core shape lowers sound level while maintaining maximum power output
Patented canister shape increases internal volume for more sound absorbing material
Patented chamber design to enhance and refine exhaust pressure
Innovative rear endcap for simple installation of tuning tip inserts or spark arrestor
Meets AMA and FIM sound requirements
Compatible with stock or FMF header
QuietCore 94dB insert included, spark arrestor available separately
Maintenance made easy with the removal of 4 screws on the front endcap
