Product Details

The FMF 042408 SX Style MegaBomb Header represents advanced exhaust technology engineered for maximum performance gains in motocross and supercross applications. This premium titanium header incorporates FMF's patented MegaBomb technology to deliver measurable power increases across the entire RPM range.

Key Features:

  • Titanium construction provides exceptional strength while reducing weight
  • MegaBomb technology produces up to 3 horsepower gain over stock
  • Optimized for low-end to mid-range power delivery ideal for Supercross racing
  • Reduces sound output by up to 1.5dB compared to stock headers
  • Produces long header torque with short header over-rev characteristics
  • Compatible with FMF Racing slip-on mufflers for complete exhaust systems
  • Used by factory racing teams in professional competition

The MegaBomb header utilizes a resonator chamber design that enhances exhaust gas flow while simultaneously reducing noise levels. By positioning the expansion chamber at a critical point in the exhaust system, the MegaBomb creates optimal pressure waves that translate to tangible performance improvements throughout the powerband. This closed-course competition header is designed for riders demanding the ultimate in four-stroke exhaust performance.
