Designed with precision, this muffler features a Hi-Flo end cap that boosts overall exhaust flow, resulting in increased power and acceleration. The computer-designed and dyno-tested construction ensures optimal compatibility and performance across various 4-stroke applications. The muffler's enhanced sonic evacuation facilitates a higher flow of exhaust gases, contributing to improved engine efficiency and responsiveness. Crafted from durable stainless steel, the mid-pipe seamlessly connects to the lightweight, elliptical aluminum rear can, providing both strength and reduced weight for better handling. The round perforated steel inner cores utilize Hi-Flo technology to maximize exhaust flow while minimizing backpressure, which translates directly into increased horsepower. FMF's exclusive cross-weave internal packing not only offers longevity but also delivers maximum sound dispersion, ensuring a balanced exhaust note. An optional Quiet Core insert is available for users seeking a reduction in noise levels without compromising performance. Additionally, the muffler includes a screen-type spark arrestor that maintains optimal exhaust flow and performance, making it suitable for trail and off-road riding where spark arrestor compliance is required. Whether you're seeking improved throttle response, increased power, or a quieter ride, the FMF Powercore 4 Muffler provides a reliable, high-performance upgrade for your motorcycle or ATV. Its strategic design and high-quality materials make it an excellent choice for riders demanding durability, efficiency, and enhanced sound control in one package.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHi-Flo end cap boosts overall exhaust performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComputer-designed and dyno-tested for optimal fit and function\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnhanced sonic evacuation increases exhaust gas flow for more power\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStainless steel mid-pipe for lightweight durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eElliptical aluminum can offers strategic sizing for superior output\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRound perforated steel inner cores utilize Hi-Flo technology for maximum flow\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExclusive cross-weave internal packing provides longevity and sound dispersion\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptional Quiet Core insert reduces sound levels without performance loss\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eScreen-type spark arrestor ensures safety without interrupting exhaust flow\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\u003cdiv class=\"product-template\"\u003e\n\u003cbr\u003e      \u003ch1\u003eFMF Powercore 4 Muffler 042387 – High-Performance Exhaust for 4-Stroke Engines\u003c\/h1\u003e\n\u003cbr\u003e      \u003cp\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003eThe FMF Powercore 4 Muffler (Part Number 042387) is engineered to enhance the performance of your 4-stroke motorcycle or ATV.
