FMF 044476 Titanium MegaBomb Header Yamaha YZ450F

The FMF Titanium MegaBomb Header represents advanced exhaust technology engineered to maximize performance on four-stroke motocross and off-road machines. This premium titanium header utilizes FMF's patented expansion chamber design that allows exhaust gases to expand, cool, and ramp back up at higher velocity, delivering substantial power increases throughout the RPM range.

Key Features:

• Constructed from military-grade titanium for extreme durability and lightweight performance
• Patented MegaBomb technology produces low-end torque of a long header with the over-rev of a short header
• Delivers up to 3 horsepower gains when combined with FMF slip-on mufflers
• Reduces noise levels by up to 1.5 dB compared to stock headers
• Optimized for improved bottom-to-mid range power with broader powerband
• Less susceptible to crash damage than longer header designs
• Factory team-proven technology used by professional motocross riders

The MegaBomb header is specifically designed for Motocross, Supercross, and GNCC-style riding where enhanced throttle response and stronger low-to-mid range power is critical. The titanium construction significantly reduces weight compared to stock while providing exceptional strength and heat resistance. This header can be paired with existing FMF Racing slip-on mufflers or used as part of a complete exhaust system upgrade.
