What makes one vehicle louder than the next? How can cars reduce emissions despite the staggering amount in which we drive them from place to place? It all comes down to your vehicle's exhaust system, or rather, the several components that make up the anatomy of an exhaust system. Your exhaust is hidden underneath your vehicle, so it's easy not to think about it too often (unless you're a car enthusiast obsessed with boosting performance capabilities.) However, just because an exhaust system is easy to ignore doesn't mean you should. It's important to understand the separate parts of an exhaust system to get more in tune with your vehicle. That way, if any exhaust system components fail, you'll be better prepared to talk to a mechanic. Or even better, you'll know which part to order to have a high chance of fixing the problem yourself.
