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","brand":"FMF","offers":[{"title":"Default Title","offer_id":48295402275031,"sku":"6107990","price":519.0,"currency_code":"AUD","in_stock":true}],"url":"https:\/\/nippon-performance.com.au\/products\/fmf-exhaust-41583-header-s-s-powerbomb","provider":"Nippon Performance ","version":"1.0","type":"link"}
