FMF Megabomb Stainless Header  Honda CRF 250R / RX / RWE | 2022-2025 

The FMF MegaBomb header is a popular choice among Factory Teams, particularly for Motocross, Supercross, and GNCC-style riding. Its patented design allows exhaust gasses to expand, cool, and ramp back up at a higher velocity, resulting in increased torque and a shorter header's over-rev. When used with an FMF Racing Slip-on Muffler, it can provide up to a 3-horsepower boost on a stock motor. Not only does the MegaBomb deliver more usable power, but it can also function as a pre-muffler and reduce noise levels by up to 1.5 dB.

• Less susceptible to crash damage than longer headers
• Produces long header torque and short header over-rev
• Reduces sound output as much as 1.5 dB
• Increases output from stock motor as much as 3 hp
• Compatible with FMF muffler only
• 100% made in the USA
