FMF 042400 SX Style MegaBomb Titanium Header

The FMF 042400 SX Style MegaBomb Titanium Header represents advanced four-stroke exhaust technology engineered to deliver substantial power gains across the entire RPM range. This premium header incorporates FMF's patented MegaBomb module—a unique expansion chamber positioned at a precise location in the header design to optimize exhaust flow and sonic performance.

Key Features:

• Constructed from military-grade titanium for extreme weight savings and superior durability
• Patented MegaBomb technology produces up to 3 horsepower increase over stock
• Unique midsection design delivers improved low-end to mid-range torque with broadened top-end power
• Reduces sound output by up to 1.5 dB while maintaining maximum power output
• SX Style tuning optimized for supercross and motocross applications with emphasis on low to mid-range power
• Produces long header torque characteristics with short header over-rev capabilities
• Larger midsection creates increased surface area for exhaust expansion and sound dissipation
• Used by factory racing teams in professional competition
• Designed for closed course use only

The MegaBomb header acts as a performance enhancer and pre-muffler, allowing exhaust gases to expand and contract through the resonance chamber for optimized flow. This next-generation design provides a significant bolt-on performance upgrade without requiring engine modifications, making it ideal for competitive motocross, supercross, and GNCC-style racing applications.
