What is a loud *** aftermarket exhaust I can get for my mustang?
When people turn their heads at your loud car, the majority of them are saying to themselves, "what an idiot". There are laws that limit the amount of sound your muffler can produce, and these laws exist for a reason. You do not have a right to cause hearing damage to other people just because you think it makes you look cool (when, in fact, it makes you look like a fool). Grow up.
