FMF - Megabomb Titanium Header (Gas Gas)

FMF – Megabomb Titanium Header

The FMF Megabomb Titanium Header is one of the most proven ways to boost your bike’s power, throttle response, and sound control — all in one sleek, lightweight package. Designed using FMF’s race-developed Megabomb expansion technology, this header delivers stronger low-end and midrange power while maintaining crisp top-end performance. It’s the same concept used by factory race teams worldwide for faster acceleration and better control out of corners.

Made entirely from exclusive titanium alloy, the Megabomb cuts weight and resists corrosion, all while reducing sound output by up to 1.5 dB. The unique bulged design acts like a pre-chamber, helping gases flow more efficiently and producing the low-end torque of a long header with the high-rpm pull of a short one. It’s also more compact and less prone to damage, making it ideal for racing and rugged off-road riding alike.

Why We Like It:
It’s a small change that makes a big difference. The Megabomb gives your bike that snappy, responsive feel off the bottom while keeping the tone deep and clean — and it looks straight off a factory bike.

Why It’ll Work for You:
This header improves your bike’s power where it matters most — from low-end grunt to midrange drive. You’ll feel stronger acceleration, smoother throttle response, and a bit less noise. Plus, the titanium build means less weight and longer life compared to steel systems.

Variants / Options:
Compatible with FMF Factory 4.1, Powercore, and Q4 mufflers for most motocross and off-road models.
