Electronic muffler 3 inches fits all cars with 3-inch outlets, and 90% of them are 8 cylinders. Its sound is excellent and it's new, never used. I removed it from the box. Reason for selling: a project was canceled. The price is a steal, God willing. Check the market, you won't find new at this price, and the sale will be easy, God willing. I also add that it has a cigarette lighter input, which is preferred and the best.
