FMF Racing fmF041544 - Honda TRX450R 2004-2013 Hex Q4 S/A Muffler

A 4-Stroke header system that incorporates FMF's patented Power Bomb module at a precise location in the initial stage of the header system; by positioning the "Bomb" at this key point, the expansion and contraction of exhaust sonics through the system resulting in a flow increase of nearly 10%. The surface of the perforated core lets the sound exit into the absorbing material (steel wool packing) and then allows the air to expand, cool and ramp back up at higher air pressures (RPMs). The Power Bomb is a "pre-muffler" of sorts, which helps to lower the bike's sound output because it provides more sound-absorbing surface area to allow the exhaust gases to become absorbed.

The FMF Racing fmF041544 is a 4-stroke header system designed for Honda TRX450R applications from 2004 through 2013. It incorporates FMF's patented Power Bomb module at a precise point in the initial stage of the header system. This positioning is designed to improve exhaust flow, with the product data stating a flow increase of nearly 10%.

The Power Bomb functions as a pre-muffler by providing additional sound-absorbing surface area. Exhaust sound passes through the perforated core into the steel wool packing, while the exhaust gases expand, cool and ramp back up at higher RPMs. This design helps lower the bike's sound output while supporting exhaust performance. The product is identified as EPA compliant.
