The surface of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up at higher air pressures (RPMs). The Power Bomb is a \"pre-muffler\" of sorts, which helps to lower the bike's sound output because it provides more sound-absorbing surface area to allow the exhaust gases to become absorbed.\n\u003cp\u003eEnhance your Kawasaki KX250F and KX250X models from 2021 to 2024 with the FMF Racing Hex Q4 Steel Slip-On Muffler, part number 042393. This high-performance exhaust system is designed to improve exhaust flow efficiency by nearly 10% through the integration of FMF's patented Power Bomb module, strategically positioned within the header system. This innovative feature acts as a pre-muffler, increasing sound absorption and reducing overall noise output while maintaining optimal exhaust flow for improved engine performance. The perforated core surface allows sound to exit into steel wool packing, which cools and expands the gases, contributing to a smoother and more efficient exhaust process. The durable steel construction ensures longevity and resistance to harsh riding conditions, making it suitable for demanding off-road environments. This system is compliant with EPA standards and is not CARB approved, making it ideal for riders seeking a reliable upgrade that balances performance with sound management. Easy to install, this slip-on muffler is a perfect choice for racers and enthusiasts aiming to maximize power while adhering to noise regulations. Designed for direct fitment, it offers a straightforward upgrade to your existing exhaust setup, ensuring a seamless integration with your Kawasaki motorcycle. Whether you're looking for increased horsepower, improved throttle response, or a quieter ride, the FMF Racing Hex Q4 Muffler is engineered to deliver consistent, high-quality performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003ePatented Power Bomb module located within the header system to increase exhaust flow by nearly 10%\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePerforated core with steel wool packing for sound absorption and gas expansion\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable steel construction designed for off-road durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompliant with EPA standards, suitable for legal racing and recreational use\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEasy direct-fit installation for Kawasaki KX250F and KX250X models from 2021 to 2024\u003c\/li\u003e\u003c\/ul\u003e","brand":"FMF Racing","offers":[{"title":"Default Title","offer_id":47978376626434,"sku":"686919","price":407.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0818\/3401\/7026\/files\/178c55cabfd458bde7afdb6f89cebd0c_3f37e58e-0da8-46fd-81a2-3b6e3048df43.jpg?v=1781160700","url":"https:\/\/teamkustom.shop\/products\/fmf-racing-kawasaki-kx250f-kx250x-21-24-hex-q4-steel-slip-on-muffler-with-power-bomb-module","provider":"Teamkustom","version":"1.0","type":"link"}
