FMF Titanium Megabomb Header - Yamaha YZ450F 2023-2025
Upgrade your 4-stroke exhaust system with the FMF Titanium Megabomb Header. The Megabomb design features a resonance chamber that smooths power delivery and increases mid-range torque. This is one of the most effective bolt-on upgrades you can make to your machine.
Titanium construction saves significant weight while handling extreme exhaust temperatures. The pipe diameter and bends are optimized through extensive dyno testing to maximize exhaust scavenging and power output. Every FMF header is designed to work with stock or aftermarket mufflers.
This header fits Yamaha YZ450F (2023-2025). Installation is straightforward with direct bolt-on fitment to your cylinder head. All necessary mounting hardware is included.
FMF headers are designed to work as part of a complete exhaust system. For maximum performance gains, pair with an FMF slip-on muffler like the Factory 4.1, Powercore 4, or Q4 series.
The head pipe flange is precision-machined for a perfect seal, preventing exhaust leaks that rob power. FMF Racing has been the leader in 4-stroke exhaust technology. Ships fast from Dune Goons with next-day fulfillment.
