One of my friends got an 03' Mustang GT about a year and a half ago. He is tired of the quiet OEM exhaust so he asked me what he can do to make the car louder without voiding the warranty (when he wants to sell it back???). I didn't have an answer because we have never gotten a new car in my family. I guess it is up to the dealership where he bought it from as to what he can or can't do to the car. I am in unfamiliar territory here and any thoughts and suggestions about what he could do (mods) would be welcome.
