FMF 045622 MegaBomb Header - Stainless Steel for KTM 350 SX-F

The FMF MegaBomb Header is the ultimate power booster for your dirt bike, featuring patented resonance chamber technology that delivers exceptional performance gains. Constructed from high-quality 304 stainless steel, this header combines durability with proven power-enhancing design.

Key Performance Benefits:

• Improved bottom to mid-range power delivery
• Produces the low-end torque of a longer header combined with the over-rev of a short header
• Can deliver up to 3 horsepower gains when paired with an FMF slip-on muffler
• Reduces sound output by as much as 1.5 dB compared to stock
• Less susceptible to crash damage than traditional long headers

Advanced Technology:

• Patented expansion chamber allows exhaust gases to expand, cool, and ramp back up at higher velocity
• Updated resonance chamber technology optimizes exhaust flow dynamics
• Acts as a pre-muffler to increase sound-absorbing surface area
• Single configuration design for simplified installation

The MegaBomb Plus header is specifically engineered for Motocross, Supercross, and GNCC-style riding where enhanced bottom-to-low-end response is critical. Compatible with sound-restricting mufflers, this header delivers race-proven performance while meeting noise regulations. Made in the USA by FMF Racing.

Note: Closed course use only. This header is designed for off-road racing applications.
