Peace, mercy, and blessings of God be upon you. An electronic valve is available with excellent quality, fits all cars. ((New in its box, unused)) ((It has the advantage that it is electric, not air. The air ones have many breakdowns due to the device that comes with them, and the advantage of the valve I am offering is that it comes with a switch, which is better than a remote. When you open it, the sound comes out, and when you close it, the original factory sound returns.)) The available size is 3 inches, the best size for performance and sound, and it fits all cars. Contents: 1- Thermal insulation for wires 2- Electronic valve 3- A switch that can be installed anywhere inside the car 4- An elbow is available, priced separately at 35﷼ Installation is very easy and costs less than 200﷼ at any exhaust shop. Shipping is available only via ((Aramex - Zajel - SMSA - RedBox)). The shipping cost is, of course, borne by the buyer.
