T-304 stainless steel, TIG welding, limited life guarantee, stainless steel mesh core, high-quality fiberglass packaging, all double 3.5 "round roll mufflers are installed on the airflow duct. Due to friction on the inner wall of the muffler, bends, perforated plates, sudden changes in the cross-section of the pipeline, and sound-absorbing materials, it will inevitably affect the aerodynamic characteristics of the machine. Excessive resistance can significantly reduce the power consumption or output energy of internal combustion engines, and even render the machine inoperable. Resistance loss is an indicator for evaluating the aerodynamic characteristics of a muffler.
