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 Yamaha YZ450F or WR450F with the FMF Racing Part Number 044442 Power Bomb header system, designed to improve exhaust flow and performance. This 4-stroke header incorporates FMF's patented Power Bomb module strategically positioned in the initial stage of the header, which increases exhaust flow efficiency by nearly 10%. The Power Bomb acts as a pre-muffler, utilizing its perforated core surface to allow sound waves to escape into steel wool packing, thereby reducing noise levels without sacrificing performance. This design also aids in cooling and expanding exhaust gases at higher RPMs, resulting in smoother power delivery and better throttle response, especially useful during intense riding conditions.\u003c\/p\u003e\u003cp\u003eConstructed with high-quality materials, the FMF Racing header is engineered for durability and optimal fit on Yamaha YZ450F and WR450F models from 2018 through 2021. Its precise placement of the Power Bomb module ensures maximum effectiveness in exhaust flow and sound absorption. The system complies with EPA standards and does not require carb acknowledgment, making it a straightforward upgrade for riders seeking increased power and a quieter ride. Installation is straightforward, fitting select Yamaha models with no need for additional modifications, ensuring a seamless upgrade.\u003c\/p\u003e\u003cp\u003eThis header system is an excellent choice for riders looking to boost their bike’s performance, reduce noise output, and enjoy improved exhaust efficiency. Designed for durability and precise fitment, the FMF Racing Power Bomb header maximizes your motorcycle’s potential while maintaining compliance with environmental standards. Whether for competitive racing or recreational riding, this system offers a significant upgrade to your Yamaha's exhaust setup, delivering enhanced power, sound control, and reliability.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003ePatented Power Bomb module increases exhaust flow by nearly 10% for improved performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStrategically positioned in the initial stage of the header for maximum efficiency\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSound absorption design reduces noise levels without compromising power\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed with durable materials for long-lasting performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFits multiple Yamaha YZ450F and WR450F models from 2018 to 2021 for versatile application\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComplies with EPA standards and requires no carb acknowledgment for ease of installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnhances throttle response and exhaust flow for a smoother ride\u003c\/li\u003e\u003c\/ul\u003e","brand":"FMF Racing","offers":[{"title":"Default Title","offer_id":47978374529282,"sku":"686934","price":407.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0818\/3401\/7026\/files\/178c55cabfd458bde7afdb6f89cebd0c_fce3ba85-348d-4680-ba53-7d6a15575aed.jpg?v=1781160458","url":"https:\/\/teamkustom.shop\/products\/fmf-racing-power-bomb-header-system-for-yamaha-yz450f-and-wr450f-models","provider":"Teamkustom","version":"1.0","type":"link"}
