Product Details

This is the FMF Racing Hex Q4 S/A Muffler, specifically made for your 2019-2021 Yamaha YZ250F. It's designed to give you that FMF performance feel while keeping the sound levels down, making it a solid choice for trail riding or tracks where noise is a concern.

Developed through years of off-road racing, this muffler is built to handle tough conditions. It's constructed using aircraft-grade aluminum for the body and high-strength stainless steel for the internal components and mounting points. This combination means it's well-built and should hold up to the vibrations and impacts of riding. Most models keep sound output at or below 96dB, with many staying under 94dB, which is a notable improvement for noise-sensitive areas.

You can use this muffler with your stock Yamaha header pipe or pair it with an FMF header for potentially improved performance. It's a direct fit for the specified YZ250F model years, meaning installation should be straightforward.
