Actually the flowmaster do have mopre of a ricey sound to them. Magnaflow and Borla, which are more expensive, have a little deeper sound. I used to have a 98 v6 mustang, and what I did was I bought a 12 inch glasspack and that was it and it gave it more of a deeper sound to it. I didnt have a lot of money to spend and I didnt want to put money into that car seeing as now I have an 07 GT. But I honestly would spend the extra money and get something that sounds good. Go onto youtube and just search for different clips of exhaust. Good luck, and hope I helped
