I had a set of Flowmaster 50 series on my 1968 Mustang Convertible. They sounded fine but the drone killed me. I got rid of them and went to a set of Magnaflow mufflers. They soud quite a bit louder but nice. They have a raspy sound to them when you get into it. My car has a supercharged 333 SBF. I like them but my wife says they are too loud and can hear me from a mile away when I come home.
