   GRWA Car Exhaust Muffler for HKS 

^{GRWA stainless steel exhaust car muffler include: resistance muffler, resistive muffler, microperforated panel muffler. The first use of the muffler is to use the abrupt change of the pipeline cross section (ie, the change of the acoustic impedance) so that the acoustic wave propagated along the pipe can be reflected back toward the sound source, so that the sound energy can be reflected back to the original place; the car muffler secondly uses the reflection of several interfaces to make the original A forward propagating sound wave is returned to its origin, and it is folded back and forward again. This point merges with the second forward propagating sound wave that has not yet been reflected, and both are equal in amplitude and 180 degrees out of phase. Odd multiples, which cancel each other out.}
