FMF Megabomb Header - Kawasaki KX250F 2025
Upgrade your 4-stroke exhaust system with the FMF Megabomb Header. The Megabomb design features a resonance chamber that smooths power delivery and increases mid-range torque. This is one of the most effective bolt-on upgrades for your machine.
Stainless steel construction provides excellent durability and corrosion resistance. The pipe diameter and bends are optimized through extensive dyno testing to maximize exhaust scavenging and power output. Every FMF header is designed to work with stock or aftermarket mufflers.
This header fits Kawasaki KX250F (2025). Installation is straightforward with direct bolt-on fitment to your cylinder head. All necessary mounting hardware is included. The head pipe flange is precision-machined for a perfect seal.
FMF headers are designed to work as part of a complete exhaust system. For maximum performance gains, pair with an FMF slip-on muffler like the Factory 4.1, Powercore 4, or Q4 series.
