FMF - 044481 - Megabomb Head Pipe with Mid Pipe - '26 Yamaha YZ450F
Riders running sound-restricted mufflers on the 2026 Yamaha YZ450F can pick up real low-end response with FMF's Megabomb Head Pipe with Mid Pipe, a design that blends the bottom-end pull of a longer header with the snappy top-end of a short one. The tucked, compact shape stays less exposed to rock strikes and trail damage than a full-length header, while sound output drops by as much as 1.5 dB when paired with a quiet muffler. The mid pipe is included for a complete single-sided exhaust setup. Closed course competition use only.
