FMF 042407 MegaBomb Stainless Steel Header Kawasaki KX250F 2025

The FMF 042407 MegaBomb Stainless Steel Header represents advanced exhaust engineering designed to maximize performance on your 2025 Kawasaki KX250F. This header incorporates FMF's patented MegaBomb technology, featuring a unique mid-section chamber that allows exhaust gases to expand, cool, and accelerate at higher velocities for substantial power gains throughout the RPM range.

Key Features:

• Improved bottom-to-mid range power and torque delivery
• Enhanced top-end performance with improved over-rev characteristics
• Reduces sound output by as much as 1.5 dB compared to stock
• Durable stainless steel construction for long-lasting performance
• Less susceptible to crash damage than longer header designs
• Lightweight design at approximately 2.4 lbs
• 100% made in the USA
• Compatible with FMF slip-on mufflers for optimal performance

The MegaBomb header is the top choice for factory racing teams and serious riders competing in Motocross, Supercross, and GNCC events where maximum bottom-to-mid range response is critical. When paired with an FMF Racing slip-on muffler, power gains of up to 3 horsepower can be achieved even on a stock motor. The patented chamber design delivers the torque characteristics of a longer header while maintaining the healthy over-rev of a shorter header, giving you the best of both worlds.
