FMF Racing - FMF042388 - Kawasaki KLX300R 2020-2021 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 Q4 S/A Muffler is designed for the 2020-2021 Kawasaki KLX300R. This 4-stroke exhaust system incorporates FMF's patented Power Bomb module at a precise location in the initial stage of the header system. The Power Bomb helps increase exhaust flow by nearly 10% by managing the expansion and contraction of exhaust pressure through the system.

The perforated core allows sound to pass into the steel wool packing, where it is absorbed before the exhaust gases expand, cool and ramp back up at higher RPMs. Acting as a pre-muffler, the Power Bomb provides additional sound-absorbing surface area to help lower the bike's sound output. The FMF042388 is listed as EPA compliant and fits the 2020 and 2021 Kawasaki KLX300R.
