This high-performance header is designed for serious riders seeking an edge on the track, optimizing exhaust flow for a broader, more potent powerband.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe FMF Megabomb Stainless Steel 4-Stroke Exhaust Header is a revolutionary design that has redefined exhaust performance for 4-stroke machines. Its unique spherical chamber, or \"Megabomb,\" acts as a pre-muffler, significantly boosting low-to-mid range power while broadening the overall powerband. This innovative design also helps to reduce sound output by up to 1.5 dB, allowing for a more aggressive yet compliant riding experience on closed courses. Crafted from durable stainless steel, this header is built to withstand the rigors of off-road and motocross racing, ensuring longevity and consistent performance. It's specifically engineered to integrate seamlessly with FMF silencers, forming a complete, high-performance exhaust system. While optimized for current racing standards, it's important to note its future compatibility with evolving FIM sound regulations. This header is designed for specific 4-stroke models, including the YZ250F from 2027 onwards, ensuring precise fitment and maximum output.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRevolutionary Megabomb Design:\u003c\/strong\u003e Patented technology that significantly enhances low-to-mid range power, broadens the powerband, and reduces sound output compared to traditional headers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Stainless Steel Construction:\u003c\/strong\u003e Built for extreme conditions, providing superior strength, corrosion resistance, and long-lasting performance on the track.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized for 4-Stroke Performance:\u003c\/strong\u003e Specifically tuned to maximize the output of 4-stroke engines, delivering a noticeable boost in throttle response and horsepower.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeamless FMF Silencer Integration:\u003c\/strong\u003e Engineered to perfectly match FMF silencers, ensuring optimal exhaust flow and a complete, high-performance system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompetition-Ready Design:\u003c\/strong\u003e Developed for closed course use, offering peak performance for racing and aggressive off-road riding.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: Stainless Steel\u003c\/li\u003e\n\u003cli\u003eProduct Type: Exhaust Header\u003c\/li\u003e\n\u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to Know\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThis FMF Megabomb header is intended for closed course use only.\u003c\/li\u003e\n\u003cli\u003eRequires an FMF silencer for proper fitment and optimal performance.\u003c\/li\u003e\n\u003cli\u003ePlease note: This product will not pass 2025 FIM sound regulations.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FMF","offers":[{"title":"Default Title","offer_id":64330312417610,"sku":"18220688","price":4859.0,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/118694aa52a3c5083880ef41af269698.webp?v=1794338694","url":"https:\/\/partsdenmark.dk\/products\/fmf-megabomb-stainless-steel-4-stroke-exhaust-header","provider":"Parts Denmark","version":"1.0","type":"link"}
