Made of durable stainless steel with an anti-slip texture design for enhanced grip.Compatible with exhaust pipes with an outer diameter of 76mm.Electronic signal-driven valve for faster response speed compared to traditional vacuum valves (millisecond level switching).High-temperature resistant connection harness included, featuring an anti-drop plug for secure linkage with the in-car ECU or dedicated remote control.Clamp-type fixation for easy installation without welding, suitable for most gasoline models, balancing convenience and controllable exhaust.The main body is made of stainless steel material (with anti-slip texture design on the surface), suitable for exhaust pipes with an outer diameter of 76mm. The valve is driven to open and close by electronic signals, and the response speed is faster than traditional vacuum valves (millisecond level switching). The kit includes a high-temperature resistant connection harness (with anti-drop plug) that supports linkage with the in-car ECU or dedicated remote control: the valve can be kept closed for daily commuting, maintaining factory silence; Automatically/manually opening the valve during rapid acceleration to widen the exhaust channel can not only release the sound of motion but also assist in improving power output efficiency. The installation adopts clamp-type fixation (no welding required), which is suitable for most gasoline models and is a modified component that balances convenient installation and controllable exhaust.Color: BlackMaterial: Stainless SteelPackage Contents:1xCar Exhaust Pipe Electronic Valve KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
