Optional Quiet Core insert will provide a decrease in sound level if desired
Elliptical aluminum can offers strategic sizing for superior performance
FMF’s exclusive cross-weave internal packing provides longevity and maximum sound dispersement
Finally, the PowerCore 4 SA system is the power standard via square inner-core technology; big weight savings over stock
The PowerCore 4 SA system’s strategic ports allow the sonics to evacuate more effectively with the computer-designed Performance Flow end cap
PowerCore 4 SA features a patented screen-type spark arrestor that is approved by the U.S.F.S. and does not interrupt exhaust flow so there’s no performance loss
Computer designed and dyno tested for every 4-stroke application
Standard Hi-Flo 2” end cap boosts all-around performance; optional smaller 1 3/4” end cap smooths power delivery; spark arrestor module adds off-road versatility
New modular end cap allows easy tuning alterations
Square or round (depending on the machine) perforated steel inner cores make for optimum flow, using hi-flo technology
A stainless steel mid-pipe mates to the computer-designed aluminum rear can for lightweight durability
Enhanced sonic evacuation delivers a higher flow of exhaust gases which increases power
