Product Details

This FMF Racing Q4 S/A muffler is made for your 2021-2023 Honda CRF450R or CRF450RX. It's designed to help your bike breathe a little easier while also reducing the noise level.

The key to this muffler is FMF's patented Power Bomb module, which is integrated into the header system. By placing it at a specific point, it helps manage the exhaust sonics, leading to an almost 10% increase in flow. The perforated core inside allows sound waves to pass through to the steel wool packing, where they are absorbed. This module acts like a pre-muffler, giving the exhaust gases more surface area to cool and expand, which in turn lowers the overall sound output of your bike.
