About this part

Product Details

FMF Racing is well-known for building performance exhaust systems, and this Hex Q4 S/A Muffler is a solid option for your Honda TRX450R from 2004 to 2014. This muffler is designed to work with FMF's header systems, incorporating their patented Power Bomb module. This module is placed strategically in the header to increase exhaust flow by nearly 10% by managing the expansion and contraction of exhaust sonics.

The perforated core inside the muffler allows sound waves to exit into the steel wool packing. This process helps the air expand and cool, then ramp back up at higher RPMs. Think of the Power Bomb as a pre-muffler; it adds more surface area for sound absorption, which helps to lower the overall sound output of your ATV. This well-built muffler aims to give you improved performance without excessive noise.
