FMF - Megabomb Titanium Header (Yamaha)

FMF – Megabomb Titanium Header

The FMF Megabomb Titanium Header is one of FMF’s most effective bolt-on power upgrades — designed to give your bike stronger low-end torque, smoother midrange pull, and a noticeable boost in throttle response. Engineered with FMF’s race-proven Megabomb technology, this header expands and cools exhaust gases to improve flow and increase performance without raising sound levels.

Constructed entirely from lightweight titanium, the Megabomb is both strong and corrosion-resistant while saving significant weight over stock. Its unique bulged design acts like a pre-chamber, improving scavenging and delivering the low-end grunt of a long header with the high-rpm power of a short one. It also helps reduce sound output by up to 1.5dB, making it an excellent match for sound-restricted tracks or off-road areas.

Why We Like It:
It’s the easiest way to unlock more usable power without adding noise. The Megabomb smooths throttle response, adds punch where you need it most, and gives your bike that clean, factory look.

Why It’ll Work for You:
This header improves how your bike builds and delivers power — stronger off the bottom, cleaner through the mid, and more responsive everywhere. It’s lighter, tougher, and less prone to damage than long headers, and it pairs perfectly with FMF slip-ons for a full performance upgrade.

Variants / Options:
Available for a range of modern motocross and off-road models. Compatible with FMF Factory 4.1 and Powercore systems.
