Features: New modular end cap allows easy tuning alterations. 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. Computer designed and dyno tested for every 4-stroke application. Enhanced sonic evacuation delivers a higher flow of exhaust gases, which increases power. A stainless steel mid-pipe mates to the computer-designed aluminum rear can for lightweight durability. Square or round (depending on the machine) perforated steel inner cores make for optimum flow, using hi-flo technology. FMF's exclusive cross-weave internal packing provides longevity and maximum sound dispersion. Elliptical aluminum can offers strategic sizing for superior performance. Optional Quiet Core insert will provide a decrease in sound level if desired. PowerCore 4 SA (spark arrestor) 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. The PowerCore 4 SA system's strategic ports allow the sonics to evacuate more effectively with the computer-designed Performance Flow end cap. NOTE: Will not pass 2025 FIM sound regulation.
