The silver muffler, also known as an acoustic filter, works by having a pair of pipes of different lengths that branch off and then converge. The length difference between the two pipes is half the wavelength of the sound waves emitted by the car, which causes the two sound waves to interfere and cancel each other out, reducing the sound intensity. This silences the sound, making it useful for various passenger vehicles. The silver muffler, also known as a "loud drum," model A0662, is made of stainless steel and measures 60CM x 20CM x 20CM. It is available in silver and is often used in various passenger vehicles. It not only has a strong decorative effect but also has strong practicality. The minimum order quantity is 10 pieces, and the packing quantity is 1 piece per case. The wholesale reference price is 450 yuan per piece.
