FMF Power Bomb Stainless Steel Header Pipe 041034 for 2002–2003 Honda CRF450R

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 Power Bomb stainless steel header pipe is a performance-focused four-stroke exhaust component designed for the 2002 and 2003 Honda CRF450R. Featuring FMF’s integrated Power Bomb chamber, this header creates additional surface area within the exhaust system to help reduce sound output while supporting improved exhaust flow. The result is a more efficient exhaust pulse transition and stronger power delivery across the usable engine range.

The Power Bomb design acts as a pre-muffler by allowing exhaust gases to expand, cool, and move through the perforated core before returning to higher-pressure flow. This configuration helps lower decibel levels and contributes to an increase in exhaust flow of nearly 10 percent, depending on the overall exhaust system and engine setup. The header is tuned for responsive bottom-to-midrange performance, making it well suited to motocross applications where controllable acceleration and usable power are important.

Designed for practical service access, the FMF Power Bomb header allows full access to the Honda CRF450R oil filter area during routine maintenance. Its stainless steel construction is intended to provide durability in demanding riding conditions. This product is manufactured by FMF and is identified by manufacturer part number 041034 and vendor part number 041034. Fitment includes the 2002 Honda CRF450R and 2003 Honda CRF450R. Confirm the motorcycle model year and existing exhaust configuration before installation.
