A \"pre muffler\" of sorts, the Power Bomb actually lowers sound output because it creates more surface area to absorb the sound medium (exhaust). The surface area 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 with the higher pressure air. The result? The FMF Power Bomb is instrumental in reducing the decibel level on any four stroke and because of the expansion and contraction on exhaust through the system, the flow has been increased by nearly 10%. That means more power throughout the range.\n\u003cp\u003eThe FMF Power Bomb Header SS (Part Number: 042389) is engineered specifically for the 2021 Kawasaki KX250F, delivering enhanced performance and reduced noise levels. Constructed from high-quality stainless steel, this four-stroke header features a precisely placed bulge in the header system that functions as a 'pre muffler,' effectively lowering sound output without sacrificing power. The unique perforated core increases surface area, allowing sound waves to be absorbed by the steel wool packing and facilitating better expansion and cooling of exhaust gases. This design results in quieter operation and a more refined riding experience while maintaining optimal performance.\u003cbr\u003eThe Power Bomb header is tuned for bottom to mid-range power, ensuring improved torque and acceleration where it matters most during riding. Its innovative expansion and contraction design enhances exhaust flow by nearly 10%, translating into increased power across the entire RPM range. This performance gain is achieved without compromising durability or reliability, making it a top choice among enthusiasts seeking both sound reduction and horsepower benefits.\u003cbr\u003eAdditionally, the FMF Power Bomb header provides full service access to the oil filter, simplifying maintenance and ensuring longevity of your exhaust system. Its precise fit and high-quality materials make it a durable upgrade that enhances your Kawasaki KX250F’s overall performance and sound profile. Whether you're aiming to improve your bike's response or reduce noise emissions, this header is designed to meet those demands with professional-grade engineering and craftsmanship.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eTuned for bottom to mid-range performance gains\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReduces sound output through innovative bulge and absorption design\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncreases exhaust flow by nearly 10% for improved power\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed from durable stainless steel for longevity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for full service access to oil filter for easier maintenance\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFits,\u003cbr\u003e\nKawasaki KX250F 2021","brand":"FMF","offers":[{"title":"Default Title","offer_id":45191300284611,"sku":"79-42389","price":249.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/7d30-6123d32ea66e0.jpg?v=1779559199","url":"https:\/\/kellymotorsport.com\/products\/fmf-power-bomb-header-ss-for-kawasaki-kx250f-2021-performance-exhaust-header-with-sound-dampening","provider":"Kelly Motorsports","version":"1.0","type":"link"}
