FMF 041577 MegaBomb Stainless Steel Header Pipe

The FMF MegaBomb Header represents breakthrough engineering in exhaust technology for four-stroke dirt bikes. This stainless steel header pipe utilizes FMF's proprietary MegaBomb technology to deliver up to 3 horsepower gains when paired with an FMF slip-on muffler, while simultaneously reducing sound output by as much as 1.5 dB.

Key Features:

• Premium 304 stainless steel construction for durability and corrosion resistance
• Produces both long header torque characteristics and short header over-rev benefits
• Enhanced low-end to mid-range power gains with broader mid to top-end power curve
• Enlarged mid-section creates greater surface area for exhaust expansion and sound dissipation
• Shorter overall length makes it less susceptible to crash damage than traditional long headers
• Works effectively with sound-restricting mufflers for track compliance
• Ideal for Motocross, Supercross, and GNCC-style trail applications
• Used by professional factory race teams worldwide

The MegaBomb technology works by strategically positioning an expansion chamber at a precise location in the header, allowing exhaust gases to expand and contract for optimized flow and power delivery. This innovative design delivers the performance benefits of both long and short header configurations in a single, compact package. Sold individually with natural stainless steel finish.
