Product Details

The FMF Racing Hex Q4 S/A Muffler uses a patented Power Bomb module, strategically placed in the header system. This design choice is key to how it functions: it creates an expansion and contraction of exhaust sonics, which results in a flow increase of nearly 10%. The perforated core surface allows sound to exit into the steel wool packing, then the air expands and cools before ramping back up at higher RPMs. Think of the Power Bomb as a pre-muffler; it adds more sound-absorbing surface area, helping to reduce the bike's overall sound output.

This well-built muffler is designed to integrate with your CRF250R's existing header system. The construction aims to provide a noticeable improvement in exhaust flow, contributing to better overall performance. It’s a solid option if you’re looking to fine-tune your bike's exhaust note and efficiency.
