PowerBomb Exhaust Header 00-22 Kawasaki Suzuki 400 KLX DR-Z R SR S SM - FMF 040038

The FMF Racing PowerBomb 040038 is a precision-engineered four-stroke stainless steel header designed to maximise exhaust flow and performance. Incorporating FMF’s patented PowerBomb module, this header strategically expands and contracts exhaust gases to deliver a significant 10% flow increase. The unique PowerBomb chamber works as a pre-muffler, aiding in the reduction of sound output while enhancing velocity for improved throttle response. Specifically developed for closed-course applications, it offers riders a measurable boost in power and efficiency with robust stainless steel construction for durability.
