This system features a modular end cap that allows for easy tuning adjustments, providing riders the flexibility to optimize power delivery for different riding conditions. The standard Hi-Flo 2-inch end cap improves overall exhaust flow, boosting engine performance, while an optional smaller 1-3\/4-inch end cap smooths power output for a more refined ride. An integrated spark arrestor module adds off-road versatility, making it suitable for trail riding and competitive environments.\u003cbr\u003eConstructed with computer-aided design and dyno-tested for compatibility with various 4-stroke applications, this exhaust system ensures reliable power gains. Enhanced sonic evacuation technology delivers higher exhaust flow, resulting in increased horsepower and torque. The stainless steel mid-pipe pairs seamlessly with the lightweight aluminum rear can, combining durability with reduced weight for better handling. Perforated steel inner cores, whether square or round depending on the machine, utilize Hi-Flo technology to maximize airflow, while FMF's exclusive cross-weave internal packing provides long-lasting sound quality and maximum noise dispersion.\u003cbr\u003eThe elliptical aluminum can is strategically sized to optimize performance, contributing to a balanced power curve. For riders seeking quieter operation, an optional Quiet Core insert can be installed to reduce noise levels without sacrificing performance. The PowerCore 4 SA features a patented screen-type spark arrestor approved by the U.S. Forest Service, maintaining safety compliance without restricting exhaust flow. Its strategically designed ports facilitate efficient sonic evacuation, further enhancing engine performance through the computer-designed Performance Flow end cap. Overall, this exhaust system offers a combination of performance, durability, and versatility for serious off-road riders and enthusiasts alike.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eModular end cap for easy tuning adjustments\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStandard Hi-Flo 2-inch end cap for improved performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptional smaller 1-3\/4-inch end cap for smoother power delivery\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSpark arrestor module adds off-road versatility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComputer-designed and dyno-tested for 4-stroke applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnhanced sonic evacuation technology increases exhaust flow and power\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStainless steel mid-pipe paired with lightweight aluminum rear can for durability and reduced weight\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePerforated steel inner cores (square or round) utilizing Hi-Flo technology for maximum airflow\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExclusive cross-weave internal packing for longevity and sound dispersion\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eElliptical aluminum can for optimized performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptional Quiet Core insert reduces noise levels without performance loss\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePowerCore 4 SA features a USFS-approved spark arrestor with no flow restriction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStrategic port design improves sonic evacuation and overall engine performance\u003c\/li\u003e\u003c\/ul\u003e","brand":"FMF","offers":[{"title":"Default Title","offer_id":45974692856005,"sku":"18300193","price":278.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/234433.png?v=1773893197","url":"https:\/\/btqllc.com\/products\/fmf-powercore-4-exhaust-system-041244-for-4-stroke-engines","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
