Hashem - I would go one step further. The Qx4 stock exhaust has two mufflers. I would go get a custom exhaust from stillen and replace are restrictive exhaust system. You'll gain more power than just replacing the one muffler. I see you are in Lebanon, I don't know if you have access to our resources but, I would look into seeing if some of our US performance dealers will except over seas orders.
