Will this header fit my stock muffler?

Yes, this FMF Racing PowerBomb header is designed to integrate with your Yamaha YZ250F's stock muffler. It's a common upgrade path for riders looking for improved performance without replacing the entire exhaust system.

What is the PowerBomb module?

The PowerBomb module is a patented chamber welded into the header pipe. It allows exhaust gases to expand and cool before re-entering the main flow, which helps improve overall exhaust flow and engine performance.

What material is the header made from?

This header is constructed from stainless steel. This material is chosen for its durability and resistance to the high temperatures and corrosive elements common in exhaust systems.

Product Details

If you're looking to get more out of your 2007-2009 Yamaha YZ250F's engine, this FMF Racing PowerBomb header is a solid option. It's designed to work with your stock muffler, making it an easier upgrade than a full system. The main job of this header is to help your engine breathe better by getting exhaust gases out more efficiently.

The key feature here is FMF's patented PowerBomb module. It's essentially an extra chamber welded into the header pipe at a specific spot. This chamber lets exhaust gases expand and cool slightly before re-entering the main flow at velocity. This process helps increase exhaust flow by up to 10%, which can lead to improved throttle response and a bit more power across the RPM range. The header itself is made from stainless steel, which holds up well against heat and corrosion.

This header is a direct fit for the 2007 through 2009 Yamaha YZ250F models. It's a popular choice for riders looking for a noticeable improvement without the complexity of a full exhaust system replacement.
