It all depends on what you want first. Sound or appearance? If I had to choose, I'd pick sound. Save some money and get a pair of good mufflers first. Then get a mid pipe. Be carefull on the setup you choose cuz some setups don't go good together. Do some research and read what other Mustang owners have to say about certain products and also try to find video/audio clips of different exhausts.(YouTube) This way you won't waste money if you buy something that you don't like. Like me!! I've spent probably over $2000 trying to find the best setup that sounds good to my ears not anyone else. What someone thinks is good is not always the case with others. That's my two cents. Take it for what it's worth. Good luck on the path you choose to do first.
