No No No No No. It does not sound like a V8. Windows up, very pleasent sound, you can still hold a conversation at normal level. It has a very deep rumble sound to it. Much nicer than the STI. If I were you, I would leave the stock resonator on. It might just be a bit to loud. I left mine on, and my wife really likes it. I was very concerned about her and the exhaust sound. PASSED With flying colors!
