This advanced design increases exhaust flow by nearly 10% by utilising sonic expansion and contraction within the outer chamber, significantly improving horsepower and velocity. The PowerBomb also acts as a pre-muffler, helping to reduce overall sound output by expanding the exhaust gases and increasing sound-absorbing surface area. Available in stainless steel construction, it is ideal for riders seeking a substantial boost in performance and throttle response.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePatented PowerBomb module enhances exhaust flow and power by up to 10%\u003c\/li\u003e\n\u003cli\u003eSonic expansion chamber acts as a pre-muffler, reducing sound output\u003c\/li\u003e\n\u003cli\u003eStainless steel construction for strength and durability\u003c\/li\u003e\n\u003cli\u003eDesigned for increased performance across the powerband\u003c\/li\u003e\n\u003cli\u003eClosed course use only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eItem ID: 044225\u003c\/li\u003e\n\u003cli\u003eType: Header\u003c\/li\u003e\n\u003cli\u003eConstruction: Stainless steel\u003c\/li\u003e\n\u003cli\u003eHeader Type: PowerBomb\u003c\/li\u003e\n\u003cli\u003eWeight: 1.7 lbs (0.77 kg)\u003c\/li\u003e\n\u003cli\u003eCarb Compliant: No\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Fitment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYamaha\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWR450F (2007–2015)\u003c\/li\u003e\n\u003cli\u003eYZ450F (2007–2009)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FMF Exhausts","offers":[{"title":"Default Title","offer_id":63417739608394,"sku":"209740","price":259.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/1249\/2874\/files\/powerbomb-exhaust-header-07-15-yamaha-450-wr-yz-f-fmf-044225-8666162.jpg?v=1788510792","url":"https:\/\/aceraceshop.co.uk\/products\/powerbomb-exhaust-header-07-15-yamaha-450-wr-yz-f-fmf-044225","provider":"ACE Race Shop","version":"1.0","type":"link"}
