{"product_id":"fmf-powerbomb-ss-header","title":"FMF Powerbomb SS Header","description":"The redesigned PowerBomb is a four-stroke header that incorporates FMF’s patented PowerBomb module at a precise location in the initial stage of the header. 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.","brand":"FMF","offers":[{"title":"Default Title","offer_id":67603483361443,"sku":"1088170003","price":225.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0560\/8620\/0483\/files\/fmf_21_pow_bom_hea_pip-mot-1088170001-7.jpg?v=1791168271","url":"https:\/\/mxpowerplay.com\/products\/fmf-powerbomb-ss-header","provider":"MX PowerPlay ","version":"1.0","type":"link"}
