{"product_id":"fmf-exhaust-40050","title":"FMF Exhaust 40050","description":"The redesigned PowerBomb is a four-stroke header that incorporates FMFs 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":51110781026588,"sku":"R0094605","price":369.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5771\/8812\/files\/fmf-6105680_aspc5o_138583c2-fca9-4a8f-8ab9-e2d50db744f2.jpg?v=1782115572","url":"https:\/\/checkout.amxsuperstorestest.com\/products\/fmf-exhaust-40050","provider":"AMX Superstores QA \u0026 Dev","version":"1.0","type":"link"}
