FMF PowerBomb Stainless Steel Header Pipe for Honda CRF250R 2006–2009, Part Number 041220

The FMF Power Bomb is a four stroke header pipe unit that has a unique bulge precisely located in the header system. A "pre muffler" of sorts, the Power Bomb actually lowers sound output because it creates more surface area to absorb the sound medium (exhaust). The surface area of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up with the higher pressure air. The result? The FMF Power Bomb is instrumental in reducing the decibel level on any four stroke and because of the expansion and contraction on exhaust through the system, the flow has been increased by nearly 10%. That means more power throughout the range.

The FMF PowerBomb Stainless Steel Header Pipe is a performance-focused four-stroke exhaust component designed for Honda CRF250R models from 2006 through 2009. Its precisely positioned PowerBomb bulge functions as a pre-muffler by increasing the available surface area for exhaust sound absorption. This design helps reduce sound output while supporting improved exhaust flow and engine performance.

The perforated core allows exhaust energy to move into the surrounding steel wool packing, where the gases can expand and cool before rejoining the higher-pressure exhaust stream. This expansion and contraction process helps increase exhaust flow by nearly 10 percent, providing stronger power delivery throughout the rev range. The header is tuned for responsive bottom-end and midrange performance, making it a practical upgrade for riders seeking improved acceleration and usable power.

Manufactured by FMF, this stainless steel header is engineered for fitment on 2006, 2007, 2008, and 2009 Honda CRF250R motorcycles.
