About this part

Product Details

If you're looking to quiet down your Beta 350, 390, 430, or 480RR from 2020-2024 while also improving exhaust flow, this FMF Racing Q4 Hex S/A Muffler is a solid option. It's designed to make your bike run a bit better and sound less aggressive.

This muffler features FMF's patented Power Bomb module, which acts like a pre-muffler. By placing it strategically in the header system, it helps increase exhaust flow by nearly 10%. The design allows sound waves to exit through the perforated core and get absorbed by the packing material, which also helps the exhaust gases cool and expand. This process not only lowers the overall sound output of your bike but also contributes to a smoother exhaust flow.

The Q4 Hex S/A Muffler is well-built with durable materials to handle the demands of off-road riding. It's a direct fit for the specified Beta models, making installation straightforward for those familiar with exhaust work.
