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