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.\n\u003cp\u003eThe FMF PowerBomb Torq stainless steel header pipe is designed to improve exhaust performance on select Honda four-stroke motocross motorcycles. Featuring FMF’s distinctive PowerBomb bulge, this header functions as a pre-muffler by increasing surface area within the exhaust system. The perforated core allows exhaust sound and gases to move into the surrounding packing material, helping reduce sound output while supporting efficient exhaust flow.\u003c\/p\u003e\u003cp\u003eThe expanded section also allows exhaust gases to cool and expand before they return to the higher-pressure portion of the system. This controlled expansion can improve throttle response and contribute to stronger power throughout the usable range, with the PowerBomb Torq configuration tuned for bottom-to-midrange performance. The stainless steel construction provides durable service for demanding off-road and motocross applications.\u003c\/p\u003e\u003cp\u003eFMF part number 041118 is designed for full access to the oil filter during routine maintenance, helping simplify service without removing the header. This FMF PowerBomb header fits 2004 and 2005 Honda CRF250R motorcycles. Verify the motorcycle model and year before installation to ensure proper fitment.
