FMF Racing Megabomb Stainless Header for Honda CRF450R/CRF450 RX 17-20/CRF450RWE 2019

FMF MegaBomb Header W/ Single Muffler Honda CRF450R / CRF450RX / CRF450R-S

The FMF MegaBomb header is the top choice for many Factory Teams and is best suited for Motocross, Supercross and GNCC style riding where more bottom to low end response is desired. The patented header design allows exhaust gasses to expand, cool and ramp back up at a higher velocity. This results in torque gains typically associated with longer headers, and the healthy over-rev of a short header. When combined with an FMF Racing Slip-on Muffler, gains of up to 3 horsepower can be achieved with a stock motor. Not only does the MegaBomb offer more usable power, it also acts as a pre-muffler and can lower noise levels by as much as 1.5 dB. 

Features:

• 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 single mufflers only
• 100% made in the USA

Weight:

• Stainless Steel 2 lbs

Note: Image is for reference only, this header is for use on bikes with a single muffler conversion.
