FMF Racing is well-known for building performance exhaust systems for off-road motorcycles. This Hex Q4 S/A muffler is designed to fit a variety of KTM and Husqvarna models, including the KTM 250/350/450 SX-F and EXC-F series, as well as the Husqvarna FC/FX 250-450-501. It incorporates FMF's patented Power Bomb module, which acts as a pre-muffler to help lower sound output by increasing the sound-absorbing surface area within the system.

The Power Bomb module is strategically placed early in the header system. This placement helps manage exhaust sonics, leading to an estimated 10% increase in flow. The perforated core allows sound waves to exit into the packing material, where they are absorbed. This design not only helps reduce the overall sound level of your bike but also contributes to improved exhaust gas flow, which can make a difference in how the engine performs at higher RPMs.

This muffler is constructed with durable materials and is designed for a direct fit on the specified KTM and Husqvarna models. It's a solid option if you're looking to improve your bike's exhaust flow and manage sound levels.
