Discharge static electricity and improve exhaust efficiency! By connecting the ground wire, the 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: 8mm Hole size: 8mm Notes ● This product is new. ● This is the price for two pieces. ● Shipped directly in an envelope without packaging.
