So before I go to the dealer, I would like to hear some peoples opinions on what may be wrong with my car. Basically when I give it gas at low rpm's, and when I let off I hear a tapping noise, almost like that of a snare drum. I cant tell if it happens any higher than 3k because of the loudness of the exhaust. A few people have told me it may be an exhaust leak which I hope it is, and not an engine problem. Only thing is, I have had a loose exhaust manifold before and it sounded way different and i knew what it was that time. Its been happening for about a week and has only gotten louder. I have an appointment with the ford dealer that i work for. They are not an authorized saleen dealer, and untill now I have bascially gotten all major service done at saleen dealers for future resale and whatnot. So secondly, should I have the work done at a saleen dealer if its a major problem with saleen parts? Any opinions would be helpful, i am extremely busy and have no time to work on the car myself?
