FMF 045640 MegaBomb Stainless Steel Header Pipe

The FMF 045640 MegaBomb header represents cutting-edge exhaust technology engineered to maximize performance on four-stroke dirt bikes. This stainless steel header incorporates FMF's patented MegaBomb technology, which delivers the low-end torque characteristics of a long header combined with the top-end over-rev capabilities of a shorter design—all in a compact, crash-resistant package.

Performance Benefits:

• 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
• Trusted by factory racing teams in Motocross, Supercross, and GNCC competition

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.
