FMF Megabomb Head Pipe with Mid Pipe (Stainless Steel) 044475 - Yamaha WR450F / YZ450F / YZ450FX 2023-2026

Product Description

Maximize your machine's exhaust scavenging with the FMF Megabomb Head Pipe, built for dedicated off-road riders demanding optimized power across the RPM range. This heavy-duty stainless steel system pairs smoothly with sound-restricting mufflers to effectively reduce sound output by as much as 1.5 dB while keeping performance at peak levels.

Crafted using advanced resonance chamber technology, this header blends the robust low-end torque benefits of a longer header with the hard-hitting top-end pull of a short header. The included mid pipe optimizes bottom to mid-range power response while offering enhanced durability against trail impacts.
