FMF – Powercore 4 Hex Muffler (Beta)
The FMF Powercore 4 Hex Muffler is built for Beta riders who want better throttle response and stronger pull without adding excess noise. Its compact hex-shaped design uses a multi-stage internal core and precision-packed materials to improve power through the entire RPM range while keeping sound levels controlled for off-road and race environments. Lighter than stock and designed to handle real trail abuse, it’s a practical upgrade for riders who want smoother performance and dependable durability.
Why We Like It
It gives the bike a cleaner, stronger feel without turning the exhaust note into something obnoxious. Power delivery improves everywhere—from slow, technical sections to long uphill pulls—and the build quality holds up well to off-road use. The spark arrestor is already built in, so it’s ready for trail systems and race events that require it.
Why It’ll Work for You
If you want better performance with manageable sound levels, this muffler makes the bike easier to ride. It broadens the power, trims weight compared to stock, and keeps you compliant with USFS sound regulations. It’s a simple bolt-on upgrade that helps the bike respond quicker and pull more consistently without extra tuning.
