The PowerBomb design features an outer chamber where exhaust pulses expand and cool before ramping back up to a higher velocity, promoting improved exhaust scavenging and overall engine efficiency.\u003c\/p\u003e\n\u003cp\u003eIn addition to improving flow, the PowerBomb acts as a pre-muffler by providing extra surface area for the exhaust sound medium, contributing to a quieter overall sound output without sacrificing performance.\u003c\/p\u003e\n\u003cp\u003eDesigned to fit Yamaha models, the 044225 header is a direct replacement for specific Yamaha configurations: YZ450F (2007–2009) and WR450F (2007–2015). It’s engineered for a precise fit on these bikes, with straightforward installation for riders familiar with exhaust work.\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eMaterial: Stainless Steel\u003c\/li\u003e \u003cli\u003ePart Number: 044225\u003c\/li\u003e \u003cli\u003eApplications: Yamaha YZ450F (2007–2009); WR450F (2007–2015)\u003c\/li\u003e \u003cli\u003eKey benefits: improved exhaust flow, enhanced throttle response, and reduced sound output via the PowerBomb chamber\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"font-family: proxima-nova, \" sans-serif font-size:=\"\" letter-spacing:=\"\"\u003eThe 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eUpgrade your Yamaha motorcycle with the FMF Racing S\/S Powerbomb Header, Part #044225.
