My cousin just got a 1989 5.0 lx Stang that had a 5.0 put in it after the 4 cylinder. He said he is not sure, but he believes that the car has some hooker mufflers on it. What do you guys think about the sound of these things? I have not heard it yet, but I would like to know what other Stang drivers think. Also he said he wants to swap them for some flowmasters....should I stop him?
