ive got 3 mustangs (a gt, a cobra, and a base model). Now ive noticed that my base is alot louder than the other two (and the gt has custom exhaust and a supercharger in it). ive checked the engine a thousand times and everything seems to be working fine. the car has no mods and i only use it on occasions where i dont need the other two's power. Its a 2003 with only 30,000 miles on it. (i even went so far as taking apart the transmission). any suggestions will be greatly appreciated.
thanks
