2008 Mustang GT Owner
This is my first car and my first mustang, and i knew what i was getting into. Recently driving it on a 1200 mile trip i quickly discovered a nearly unbearable exhaust drone in the low end of the tachometer in fifth gear. Mustangs run in the family, my mom still has her '66 289 V8 convertible and my dad had 2, an '07 GT convertible and a '11 GT Convertible, and neither had such a sound. The car is in good shape with 57k miles on it, and other than a set of vinyl stripes the previous owner put on, it is a bone stock 08 GT Convertible. I heard on similar threads that you can put dynamat down in the trunk, but being a convertible, it wont do much good. Are there any (affordable) exhaust systems that don't suffer from drone? Is it a more serious issue such as a throttle body sensor failure? I already searched around for similar threads, but none came to a solid conclusion. Thanks in advance.
