What is the PowerBomb module and how does it improve performance?

The PowerBomb module is an FMF patented design integrated into the header. It creates an outer chamber that allows exhaust gases to expand and cool before rejoining the main flow at velocity, which helps increase overall exhaust flow by up to 10%.

What material is this header made from?

This header is constructed from stainless steel, chosen for its durability and resistance to the heat and conditions typical of off-road riding.

Does this header come with all the necessary hardware for installation?

This product is the FMF Racing Powerbomb Header only. It is designed to be a direct fit replacement for your stock header, but you may need to reuse some stock hardware or purchase specific gaskets separately depending on your bike's original setup.

Product Details

This FMF Racing Powerbomb header is specifically made for your 2004-2009 and 2012-2017 Honda CRF250X. It's designed to replace your stock header and work with your existing exhaust system to help your engine breathe better. The header is constructed from stainless steel for good durability.

The key feature here is FMF's patented PowerBomb module, which is integrated into the initial section of the header. This module creates an outer chamber where exhaust gases can expand and cool before rejoining the main flow at velocity. This design helps increase exhaust flow by up to 10%, which can lead to noticeable gains in performance and a more responsive feel from your CRF250X. It's a well-built component aimed at extracting more power from your bike.

When installing this header, it's designed to be a direct fit with your stock system. You'll want to ensure all connections are sealed properly to get the most benefit from the improved flow.
