      Engines have often been compared to air pumps, because the engine that’s most efficient in terms of economy and power is the one that can get air in and out of its cylinders the easiest. That’s why most performance modifications like conical air filters, cold air intake systems, headers, and cat-back exhaust systems are aimed at making the intake and exhaust systems less restrictive. These parts increase the flow of air into the engine and ease the flow of exhaust gas out of the engine. Among these components, headers may be the most difficult to install. In this article, we’ll discuss what headers do, their different types, and how much performance they can add to your car.

      Regardless of whether you're shopping for a simple replacement muffler that delivers original equipment (OE) sound and performance or an upgraded muffler which provides a deeper growl with increased power through freer exhaust flow, you'll see choices between "direct fit" mufflers and "universal" mufflers. In this article, we'll help you understand the differences between these two styles so you can make a more informed purchase.
