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 for Yamaha YZ250F and WR250F models from 2001 to 2006 offers an innovative design that enhances both sound reduction and performance. Its unique bulge in the header system functions as a pre-muffler, significantly lowering exhaust noise by increasing the surface area to absorb sound waves. This design not only provides quieter operation but also improves exhaust flow efficiency. The perforated core allows sound to pass into absorbing material, such as steel wool packing, where it is cooled and expanded, resulting in a notable reduction in decibel levels. Additionally, this expansion and contraction of exhaust gases facilitate a nearly 10% increase in flow, translating to increased power across the engine's entire range. Constructed for durability and performance, the Power Bomb header is a popular choice among riders seeking to optimize their four-stroke motorcycle's sound and power output.\u003c\/p\u003e\u003cp\u003eDesigned with performance in mind, the Power Bomb header is tuned for bottom to mid-range performance, making it ideal for riders looking to improve responsiveness and acceleration. The header's design ensures full service access to the oil filter, simplifying maintenance without sacrificing performance. The FMF Power Bomb is a proven leader in performance headers, providing a balance of reduced noise and enhanced power that meets the demands of competitive and recreational riders alike. Whether you're upgrading your Yamaha YZ250F or WR250F, this header offers a reliable, high-quality solution to boost your motorcycle's performance and riding experience.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eTuned for bottom to mid-range performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReduces exhaust noise through innovative bulge and absorption design\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncreases exhaust flow by nearly 10%, enhancing overall power\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFull service access to oil filter for easy maintenance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed for durability and high performance in Yamaha YZ250F and WR250F models\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFits,\u003cbr\u003e\nYamaha WR250F 2001\u003cbr\u003e\nYamaha WR250F 2002\u003cbr\u003e\nYamaha WR250F 2003\u003cbr\u003e\nYamaha WR250F 2004\u003cbr\u003e\nYamaha WR250F 2005\u003cbr\u003e\nYamaha WR250F 2006\u003cbr\u003e\nYamaha WR250F 2007\u003cbr\u003e\nYamaha WR250F 2008\u003cbr\u003e\nYamaha WR250F 2009\u003cbr\u003e\nYamaha WR250F 2010\u003cbr\u003e\nYamaha WR250F 2011\u003cbr\u003e\nYamaha WR250F 2012\u003cbr\u003e\nYamaha WR250F 2013\u003cbr\u003e\nYamaha YZ250F 2001\u003cbr\u003e\nYamaha YZ250F 2002\u003cbr\u003e\nYamaha YZ250F 2003\u003cbr\u003e\nYamaha YZ250F 2004\u003cbr\u003e\nYamaha YZ250F 2005\u003cbr\u003e\nYamaha YZ250F 2006","brand":"FMF","offers":[{"title":"Default Title","offer_id":45191300612291,"sku":"79-1662","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/a274-572a8b22c26aa_aac85866-96b4-48f6-ba17-aee4e16ee4bd.jpg?v=1779559254","url":"https:\/\/kellymotorsport.com\/products\/fmf-power-bomb-header-for-yamaha-yz250f-and-wr250f-2001-2006","provider":"Kelly Motorsports","version":"1.0","type":"link"}
