FMF Powerbomb Stainless Steel Header for Kawasaki KLR650, Part 042317

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 is a performance-focused four-stroke exhaust header designed for Kawasaki KLR650 motorcycles from 2008 through 2017. Manufactured by FMF and sold under vendor part number 042317, this Powerbomb header features FMF’s integrated expansion chamber design, which acts as a pre-muffler within the header system. Its precisely positioned bulge increases surface area and helps manage exhaust sound while supporting improved exhaust flow.

The perforated core allows exhaust energy to move into the surrounding packing material, where sound is absorbed before the gases expand, cool, and re-enter the higher-pressure exhaust stream. This process helps reduce exhaust noise and can improve exhaust flow by nearly 10 percent, delivering stronger performance throughout the usable RPM range. The header is tuned for responsive bottom-to-midrange performance, making it well suited for trail riding, commuting, and general-purpose adventure use.

Designed as a direct-fit replacement for the original header on applicable motorcycles, the FMF Powerbomb provides full service access to the oil filter for easier routine maintenance. Its stainless steel construction offers durable performance in demanding riding conditions while maintaining a clean, functional appearance. Verify the motorcycle year and model before ordering to ensure proper fitment.
