FMF 045665 Stainless Steel MegaBomb Header for Beta RR 430/480

The FMF 045665 MegaBomb Header represents advanced exhaust engineering designed to deliver significant performance gains across the entire RPM range. This stainless steel header utilizes FMF's patented MegaBomb technology, featuring a unique enlarged midsection that allows exhaust gases to expand, cool, and accelerate at higher velocities for optimized power delivery.

Key Features:

• Produces up to 3 horsepower gains when combined with FMF slip-on mufflers
• Delivers long header torque characteristics with short header over-rev benefits
• Reduces sound output by as much as 1.5dB compared to stock
• Enhanced low-end to mid-range power with broadened mid-to-top end gains
• Durable stainless steel construction for long-lasting performance
• Compact design less susceptible to crash damage than longer headers
• Factory-tested technology used by professional racing teams

The enlarged midsection creates increased surface area for sound dissipation while the patented design optimizes exhaust flow dynamics. Ideal for motocross, supercross, and GNCC-style trail riding. This header is specifically engineered for Beta RR 430 and 480 four-stroke models from 2020-2026. Closed course use only.
