FMF Racing Megabomb Exhaust Header for Yamaha 044450

Turbocharge Yamaha performance with the Titanium Megabomb Header (044450). Engineered specifically for Yamaha motorcycles, this two‑piece Megabomb header optimizes exhaust flow to deliver up to 3 hp more than stock and a broader torque curve, giving immediate throttle response and stronger mid‑range punch.

Megabomb’s patent‑pending design creates a long header for strong bottom‑end torque while preserving top‑end revs, so you feel steady pull from low RPMs and crisp acceleration at higher speeds. Constructed from Premium American Metal materials, it combines lightweight titanium with durable, heat‑resistant joints to withstand demanding riding conditions.

When paired with the right FMF silencer, the Megabomb header can contribute to a quieter, deeper exhaust note—down as much as 1.5 dB—without sacrificing performance. It’s designed for easy bolt‑on installation with OEM compatibility, letting you bolt it on and ride with confidence.
