The P-Core 4 Hex muffler features FMF's patented core design that uses a perforated stainless steel inner core wrapped with high-temp fiberglass material to absorb sound while maximizing exhaust flow. The hexagonal shape allows for a larger internal volume compared to traditional round mufflers, resulting in improved mid-range power and a broader, more usable powerband. Built to withstand the rigors of aggressive motocross racing, this muffler delivers proven performance gains that riders can feel immediately.
