Your car's exhaust system consists of pipes that direct reactive exhaust gases from the engine into the air, allowing the engine to continue to function. It's important to note here that we're talking about an exhaust system, not an exhaust tip. The exhaust tip—the part of the exhaust system visible from the outside of the car—doesn't change the performance of the exhaust system; it's just a cosmetic upgrade.

However, it is a very popular one. There are many different types of exhaust tips, from round and square to intercooled and edged varieties, all of which come in many different finishes and are easy to install. Most aftermarket exhaust pipes can be screwed onto the car's original exhaust system, while some simply slide into the system itself.
