I am looking foward to getting an exhaust pipe, but I don't know what would be best for me. I don't know much about modding cars, so I am confused about what an exhaust pipe does. Can I just get the tip of an exhaust pipe where it's just chrome instead of my rusty black steel (stock) one or do I have to purchase like a whole exhaust pipe system where it produces louder sound also? What are the pros and cons of each? Does the one with the "louder" sound give any performance gains? What I really want is a minor deep sound, not so loud like all those streetcars, but just not so loud deeper sound with a new chrome tip..
