FMF 041626 Powerbomb Stainless Steel Header Pipe - 4-Stroke

The FMF PowerBomb 041626 is a performance stainless steel header pipe engineered for four-stroke motorcycles. Built around FMF's patented PowerBomb module, this header features a precisely located expansion chamber integrated into the initial stage of the header system, delivering measurable gains in exhaust flow and overall engine performance.

By positioning the PowerBomb module at a critical point in the exhaust path, the system leverages the expansion and contraction of exhaust sonics to achieve a flow increase of nearly 10%. The outer chamber allows exhaust gases to expand, cool, and accelerate back through the system at higher velocity — translating directly into more usable power throughout the RPM range.

Key Features:

• FMF patented PowerBomb expansion module integrated into the header
• Stainless steel construction for superior durability and corrosion resistance
• Acts as a "pre-muffler" to reduce overall sound output by increasing sound-absorbing surface area
• Perforated core with steel wool packing absorbs exhaust noise while improving flow
• Near 10% exhaust flow improvement over conventional headers
• Designed for full-service access to the oil filter
• Tuned for bottom-to-mid range power delivery
• Closed course use only

The FMF PowerBomb stainless steel header is an ideal upgrade for riders looking to improve exhaust flow, reduce noise, and maximize four-stroke performance. Its robust stainless steel construction ensures long-lasting reliability under demanding race and trail conditions.
