FMF Racing Powerbomb Stainless Header for Yamaha YZ250F 01-06/WR250F 01-13

FMF PowerBomb Header Yamaha YZ250F / WR250R

If you spend most of your time riding in the mid to upper RPM range the FMF PowerBomb is the header for you. The PowerBomb incorporates a patented chamber at a precise location in the initial stage of the header. This chamber allows exhaust gases to expand and then contract, resulting in nearly a 10% flow increase. Not only does the PowerBomb offer more usable mid to top end power, it also acts as a pre-muffler and can help lower exhaust sound output.

• Motocross version designed to increase mid to top end output from stock motor
• Reduces sound output

• 100% made in the USA
