FMF 045640 MegaBomb Stainless Steel Header Pipe

Manufacturer

FMF

<p>In 1973 Don Emler created FMF out of a desire to go faster. Born in Southern California as the Flying Machine Factory, FMF was set up by a youthful and exuberant twenty-two year old who found the urge to ride and race dirt bikes simply irresistible. What began as a garage operation focused on building faster bikes for himself and his riding buddies has evolved into one of the most respected names in powersports exhaust technology.</p> <h3>A Legacy Built on Innovation</h3> <p>As Donny worked on his own bike and developing engines and exhausts to make them faster, he built a name for himself around the tracks and the Southern California area, attracting up-and-coming pros like Marty Smith, Danny LaPorte and Warren Reid. For fifty years FMF has been leading in the pursuit of precision, power and speed. The brand's commitment to performance isn't just marketing—it's woven into the company's DNA, shaped by decades of racing experience and real-world testing at the highest levels of competition.</p> <p>Hand made from start to finish right here in the USA, each pipe exhibits an attention to detail and level of professional craftsmanship that is lacking in their mass produced competitors. This dedication to quality manufacturing ensures that every component meets the exacting standards riders demand, whether they're chasing podiums or exploring backcountry trails.</p> <h3>Complete Exhaust Solutions</h3> <p>FMF's product lineup addresses every aspect of exhaust performance. Their <a href="/6145-fmf-exhaust-system-kit-10727">exhaust system kits</a> offer comprehensive solutions for riders looking to transform their machine's power delivery, combining precision-engineered components that work in harmony to maximize output. The brand's <a href="/6145-fmf-exhaust-muffler-5872">exhaust mufflers</a> and <a href="/6145-fmf-mufflers-200710">mufflers</a> utilize advanced technologies to balance sound control with performance gains, meeting trail regulations without sacrificing the power advantages that make FMF legendary.</p> <p>The foundation of any great exhaust system starts with the <a href="/6145-fmf-exhaust-header-5848">exhaust header</a>, where FMF's expertise in flow dynamics and metallurgy creates measurable improvements in throttle response and horsepower. Their <a href="/6145-fmf-exhaust-pipe-10038">exhaust pipes</a> are tuned specifically for different riding styles and engine configurations, whether you need low-end torque for technical terrain or top-end power for wide-open racing.</p> <h3>Materials and Engineering Excellence</h3> <p>The use of premium materials (all produced in the US) in FMF exhaust systems such as titanium, stainless steel and carbon fiber, accomplish goals of reduced weight and improved rider ergonomics and overall aesthetics. The company's patented Resonance Chamber Technology allows for shortening the overall length of the FMF pipe, which results in reduced probability of suffering from crash damage. These engineering innovations demonstrate how FMF continues to push boundaries, creating exhaust systems that don't just perform better but also survive the punishment of aggressive riding.</p> <h3>Proven on the World Stage</h3> <p>FMF has been an ardent supporter of the world's most prestigious off-road motorcycle racing series for more than 30 years, cementing their reputation through countless victories and championships. This racing pedigree translates directly to the products available to enthusiasts, as technologies developed under the most demanding competition conditions make their way into production exhaust systems. From weekend warriors to factory-backed professionals, riders trust FMF to deliver the performance advantage that can make the difference between winning and watching from the sidelines.</p>

Product Details

The FMF 045640 MegaBomb header represents cutting-edge exhaust technology engineered to maximize performance on four-stroke dirt bikes.

  • Gains up to 3 horsepower when paired with an FMF Racing slip-on muffler
  • Enhances low-end to mid-range power while broadening mid to top-end power gains
  • Reduces noise levels by as much as 1.5 dB compared to stock
  • Produces long header torque characteristics with short header over-rev

Construction and Design:

  • Manufactured from durable 304 stainless steel for corrosion resistance
  • Features patented MegaBomb module with larger midsection for improved sound dissipation
  • Compact design reduces length to minimize damage risk during crashes
  • Single header configuration with natural finish
  • Designed specifically to fit FMF mufflers only

Ideal for Motocross, Supercross, and GNCC-style trail riding where enhanced bottom-end and mid-range power delivery provides a competitive advantage. This header is designed for closed course use only and requires an FMF Racing muffler for proper fitment and optimal performance.
