By positioning this “Bomb” at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust sonics through the system. Result is a flow increase of nearly 10%! The outer chamber in the Powerbomb allows the air to expand, cool and ramp back up at a higher velocity. Additionally, the PowerBomb is a “pre-muffler” of sorts which helps to lower the bikes sound output by providing more sound absorbing surface area for the sound medium (exhaust gases). On some models, you can choose between a moto or supercross version. The supercross version is designed for more low to mid-range power where the moto version is focused in the mid to upper RPM range.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"tab\"\u003e\n\u003clabel class=\"tab-label\" for=\"chck2\"\u003eFeatures\u003c\/label\u003e\n\u003cdiv class=\"tab-content\"\u003e\n\u003cb\u003eNotice:\u003c\/b\u003eClosed Course Use Only\u003cbr\u003e\u003cb\u003eItem ID:\u003c\/b\u003e044225\u003cbr\u003e\u003cb\u003eType:\u003c\/b\u003eHeader\u003cbr\u003e\u003cb\u003eCarb Warning:\u003c\/b\u003eno\u003cbr\u003e\u003cb\u003eHeader Const:\u003c\/b\u003eStainless Steel\u003cbr\u003e\u003cb\u003eHeader Type:\u003c\/b\u003ePowerBomb\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e1.7 lbs.\u003c\/div\u003e\n\u003cdiv class=\"tab-content\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eYAMAHA\u003c\/td\u003e\n\u003ctd\u003eWR450F\u003c\/td\u003e\n\u003ctd\u003e07-15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eYAMAHA\u003c\/td\u003e\n\u003ctd\u003eYZ450F\u003c\/td\u003e\n\u003ctd\u003e07-09\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"FMF Racing","offers":[{"title":"Default Title","offer_id":52874039230773,"sku":"FMF044225","price":219.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0873\/4697\/0933\/files\/dd84a3bd-9c18-42c6-8187-4aba0c8d4350_1800x1800_1ef3a2cc-2c67-4ebe-b9a0-bf60e188d9bc.jpg?v=1778902690","url":"https:\/\/ad-discountpowersports.com\/products\/fmf-racing-yamaha-yz450f-07-09-wr450f-07-15-ss-powerbomb-header","provider":"A\u0026D Discount Performance","version":"1.0","type":"link"}
