Discharge static electricity and improve exhaust efficiency! By connecting the ground wire, static electricity generated inside the muffler is released, reducing exhaust resistance, which has the same effect as attaching a muffler with a larger diameter. ● Exhaust gas flowing inside the muffler generates static electricity and becomes charged, hindering smooth exhaust. ● By grounding the muffler, static electricity is removed, improving exhaust efficiency, and increasing power, torque, and response. 【Specifications】 Total length: 25cm Material: Copper, braided, silver-plated Terminals: 10mm Hole size: 10mm Notes ● This is a new product. ● This is the price for two pieces. ● Since there is no packaging, it will be sent directly in an envelope.
