FMF Stainless Steel Megabomb Header for 2020+ Beta 430 and 480 4T Models

The FMF Megabomb Header is engineered to deliver noticeable gains in power, throttle response, and torque across the rev range. Constructed from durable stainless steel, the Megabomb expands exhaust volume and optimizes gas flow for improved performance without excessive noise. Its patented design pre-tunes the exhaust pressure wave for a stronger bottom and midrange, while reducing sound output compared to standard headers.
