I am looking to do my first modification on my car. I am tossing around the idea of exhaust as the first mod. Now, I love the sound of the stock tone to the mufflers. Although, I want more power and maybe a little more sound to it. What is the best way to go? I put straight pipes on my Lightning and that sounded AWESOME!!! That was also a bigger engine then the Mustang. Has anyone run straight pipes on their 4.6 and if so, is it obnoxiously loud? Should I run some sort of an exhaust system? Now remember my car is a Convertible, so it is probably going to get a lot more noise in the interior then if it were a non-convertible. Please, someone help me with this!!! Thanks in advance.
