I bought this Ford Racing Touring exhaust and I have to say they sound just great. A friend of mine, he has the Sport F.R. exhaust, after hearing mine: =>I want them too. What he told me if he didnt knew what kind of Mustang I have, he would bet it's a v8. Im very satisfied with this exhaust. Not to laud and when you have to show up .. belive me the will watch at you!
